+		  GNU LESSER GENERAL PUBLIC LICENSE
+		       Version 2.1, February 1999
+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it becomes
+a de-facto standard.  To achieve this, non-free programs must be
+allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+
+		  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control compilation
+and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+  
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at
+    least three years, to give the same user the materials
+    specified in Subsection 6a, above, for a charge no more
+    than the cost of performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under any
+particular circumstance, the balance of the section is intended to apply,
+and the section as a whole is intended to apply in other circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License may add
+an explicit geographical distribution limitation excluding those countries,
+so that distribution is permitted only in or among countries not thus
+excluded.  In such case, this License incorporates the limitation as if
+written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new

+Release Notes for Version 1.0
+--------------------------------
+-Jpeg image support added.
+-Added new tag parameters to img and legend:
+	-removeAfterRender will remove images from storage immediately. Defaults to False. NOTE: This 
+	may cause problems if your users expect to copy or save the images from the browser as some
+	browsers will put the url in the paste buffer and attempt to reload when pasted somewhere such 
+	as MS Word.
+	-forceSessionId will add jsessionid parameter to the image url. Defaults to True. This matches
+	existing functionality but now allows the option to disable this for certain use cases.
+-Supports JFC 1.0.0 Final
+	JFC no longer supports the signals chart type. This has been commented out in cewolf for now
+	because there is talk on the forum that it may come back.
+-At release time, site is not fully updated. This will come in the near future as I move the site fully to Maven2.
+	
+

+	Useful to acquire JFreeChart's ChartRenderingInfo object.
+-Fixed [ 1158392 ] Configuration object causes NPE when servlet reloads
+-Fixed chart-renderer factory problem; that if multiple charts of the same type appeared
+	on the same page they shared the same renderer, therefore if a post-processor customized
+	that renderer all charts were affected.
+-Fixed that tooltips would not appear in firefox; when the jsp page in a subdir
+	need to use /etc/overlib.js style path in config for this.

+    <description>
+        The gradientpaint tag provides a way to fill a shape with a linear 
+        color gradient pattern. If Point P1 with Color C1 and Point P2 with 
+        Color C2 are specified in user space, the Color on the P1, P2 
+        connecting line is proportionally changed from C1 to C2. Any point 
+        P not on the extended P1, P2 connecting line has the color of the 
+        point P' that is the perpendicular projection of P on the extended P1,
+        P2 connecting line. Points on the extended line outside of the P1,
+        P2 segment can be colored in one of two ways.
+        &lt;ul&gt;
+        &lt;li&gt;If the gradient is cyclic then the points on the extended 
+        P1, P2 connecting line cycle back and forth between the colors C1 
+        and C2.
+        &lt;li&gt;If the gradient is acyclic then points on the P1 side of 
+        the segment have the constant Color C1 while points on the P2 side 
+        have the constant Color C2.
+        The two colors are defined in a nested point tag of this tag.

+    <description>
+        The gradientpaint tag provides a way to fill a shape with a linear 
+        color gradient pattern. If Point P1 with Color C1 and Point P2 with 
+        Color C2 are specified in user space, the Color on the P1, P2 
+        connecting line is proportionally changed from C1 to C2. Any point 
+        P not on the extended P1, P2 connecting line has the color of the 
+        point P' that is the perpendicular projection of P on the extended P1,
+        P2 connecting line. Points on the extended line outside of the P1,
+        P2 segment can be colored in one of two ways.
+        &lt;ul&gt;
+        &lt;li&gt;If the gradient is cyclic then the points on the extended 
+        P1, P2 connecting line cycle back and forth between the colors C1 
+        and C2.
+        &lt;li&gt;If the gradient is acyclic then points on the P1 side of 
+        the segment have the constant Color C1 while points on the P2 side 
+        have the constant Color C2.
+        The two colors are defined in a nested point tag of this tag.

+    <description>
+        The gradientpaint tag provides a way to fill a shape with a linear 
+        color gradient pattern. If Point P1 with Color C1 and Point P2 with 
+        Color C2 are specified in user space, the Color on the P1, P2 
+        connecting line is proportionally changed from C1 to C2. Any point 
+        P not on the extended P1, P2 connecting line has the color of the 
+        point P' that is the perpendicular projection of P on the extended P1,
+        P2 connecting line. Points on the extended line outside of the P1,
+        P2 segment can be colored in one of two ways.
+        &lt;ul&gt;
+        &lt;li&gt;If the gradient is cyclic then the points on the extended 
+        P1, P2 connecting line cycle back and forth between the colors C1 
+        and C2.
+        &lt;li&gt;If the gradient is acyclic then points on the P1 side of 
+        the segment have the constant Color C1 while points on the P2 side 
+        have the constant Color C2.
+        The two colors are defined in a nested point tag of this tag.

+    <description>
+        The gradientpaint tag provides a way to fill a shape with a linear 
+        color gradient pattern. If Point P1 with Color C1 and Point P2 with 
+        Color C2 are specified in user space, the Color on the P1, P2 
+        connecting line is proportionally changed from C1 to C2. Any point 
+        P not on the extended P1, P2 connecting line has the color of the 
+        point P' that is the perpendicular projection of P on the extended P1,
+        P2 connecting line. Points on the extended line outside of the P1,
+        P2 segment can be colored in one of two ways.
+        &lt;ul&gt;
+        &lt;li&gt;If the gradient is cyclic then the points on the extended 
+        P1, P2 connecting line cycle back and forth between the colors C1 
+        and C2.
+        &lt;li&gt;If the gradient is acyclic then points on the P1 side of 
+        the segment have the constant Color C1 while points on the P2 side 
+        have the constant Color C2.
+        The two colors are defined in a nested point tag of this tag.

+<h1>Introduction</h1>
+<p class="Body"> Cewolf can be used inside a Servlet/JSP based web
+application to embed complex graphical charts of all kinds (e.g. line,
+pie, bar chart, plots, etc.) into a web page. Therefore it provides a
+full featured tag library to define all properties of the chart (colors,
+strokes, legend, etc.). Thus the JSP which embedds the chart is not
+polluted with any java code. Everything is described with XML conform
+tags. </p>
+<p> Cewolf is based on <a
+ href="http://www.object-refinery.com/jfreechart/">JFreeChart</a> and
+uses it's rendering engine to render the final chart image into the
+clients response stream. No files are created on server side. Everything
+is based on lightweight session objects and dynamic data analysis.
+Cewolf consists of one servlet which handles the chart rendering and a
+taglibrary which translates the chart definition included in the JSP
+into an HTML img tag which consults the rendering servlet for retrieval
+of the appropriate chart. </p>
+<p> Simce the project has been funded in the middle of 2002 there have
+been <b>more then 150.000 page views and 16.000 downloads</b>
+(Sourceforge activity max: &gt;99,7%). </p>

+<h1>Example</h1>
+<p> You can simply define a chart by including a chart tag into your JSP
+like this: </p>
+<pre>&lt;cewolf:chart <br>    id="XYChart"<br>    type="xy"<br>    title="XYChart" <br>    &lt;cewolf:gradient&gt;<br>        &lt;cewolf:point x="0" y="0" color="#FFFFFF"/&gt;<br>        &lt;cewolf:point x="0" y="300" color="#C8C8C8"/&gt;<br>    &lt;/cewolf:gradient&gt;<br>    &lt;cewolf:data&gt;<br>        &lt;cewolf:producer id="xyData"/&gt;<br>    &lt;/cewolf:data&gt;<br>&lt;/cewolf:chart&gt;<br>&lt;cewolf:img chartid="XYChart" renderer="cewolf" width="400" height="300"/&gt;<br></pre>
+<p> This results in a rendered chart like this: </p>
+<img alt="examplechart" src="img/examplexy.png">
+<p> As you can see only the view is defined in the JSP page. The model
+is produced by a so called DataProducer which must be available in the
+pageContext of the JSP. </p>

+<h1><a name="Developer Guido">Developer Guide</a></h1>
+<p> Let us assume the following (standard) scenario in which Cewolf
+might be a solution.<br>
+You have a running web application and you want to know which pages are
+most visited by your users. You want to have a vertical bar chart which
+looks like the one below </p>
+<p> <img src="img/guidevbarchart.gif" alt="verticalbar"> </p>
+<p> </p>
+<h2>1. Prepare Your Application</h2>
+<p> If you have not yet downloaded the Cewolf distribution, this is the
+point when you should do it (look at <a
+ href="http://sourceforge.net/project/showfiles.php?group_id=57282"
+ target="new">Download</a>). Put the <tt>cewolf.jar</tt> file into your
+web application's <tt>/WEB-INF/lib</tt> directory.<br>
+That should be all you have to do to prepare your application for
+Cewolf usage. If you encounter any problems in using the Cewolf tags
+(e.g. "No Tags" is displayed in your containers console) you can
+additionally put the <tt>cewolf.tld</tt> file from the distribution's <tt>etc</tt>
+directory into a directory of your choice under your web application's
+root and reference this file as the cewolf tag library from your JSPs. </p>
+<h2>2. Provide a DatasetProducer</h2>
+<p> As Cewolf uses a MVC (Model-View-Control) approach the data which
+are shown in your chart are separated from the view defined in the JSP
+page. So you can change them separately. To provide the chart with the
+correct data you must provide an object which implements the interface<tt>de.laures.cewolf.DatasetProducer</tt>.
+This object is asked to produce data every time a chart is rendered.
+Below you see an implementation of a DatasetProducer which could be used
+to provide data needed for our example scenario. </p>
+<p> </p>
+to be continued ...
+<h2>3. Install the Cewolf Servlet in your Web App</h2>
+tbd.
+<h2>4. Define the chart in your JSP</h2>
+<pre>&lt;%@page contentType="text/html"%&gt;<br>&lt;%@taglib uri='/WEB-INF/cewolf.tld' prefix='cewolf' %&gt;<br>&lt;jsp:useBean id="pageViews" class="de.laures.cewolf.example.PageViewCountData"/&gt;<br>&lt;cewolf:chart <br>    id="horizontalBarChart" <br>    title="HorizontalBarChart" <br>    renderer="servlet/chart" <br>    width="300" height="300" <br>    type="horizontalBar" <br>    xAxisLabel="Page" <br>    yAxisLabel="Views"&gt;<br>    &lt;cewolf:data producer="pageViews" /&gt;<br>&lt;/cewolf:chart&gt;<br></pre>

+<dd>While developing a web application which needed to provide some chart images Guido

+In June 2002 Guido decided to donate his library to the public and named it Cewolf.<br><br></dd>

+<dd>Essentially, this is a variation of the headless Linux server problem. 
+    If there are any Linux wizards out there (I use SuSE 7.1) to point out better solutions, I'd be happy to hear them.<br>
+
+I was not quite convinced it would be the same problem many other people had, since I _have_ an X server running. However, it is sitting there, idling away with KDM (the KDE Display Manager), and I could not find a way to make that display available to java. I tried to connect to it, tried to set xhost +, but no avail. In the end, I used (as root)
+startx -- :2
+to start another X server on display :2 (localhost is implied). Unfortunately, startx will start KDE, so the libraries are loaded into memory, but that is a minor annoyance. There might be a possibility of starting just the X server or a minor window manager (twm for example), but I tried with env WANTEDWM=twm startx -- :2 &, but KDE got loaded anyway. In essence, the Xvfb solution might just be the thing I use next time.
+<br>
+Then, all you have to do is tell Tomcat to use display 2 for painting:
+env DISPLAY=:2 bin/startup.sh
+(being in /opt/tomcat4).
+<br>

+<br>
+Generally, try to look for 'headless' on java.sun.com (be sure to include the forums!).
+<br>
+Why didn't I use the headless option of JDK1.4?
+Of course I tried, but the Cewolf classes include a call to de.laures.cewolf.util.ImageHelper, which in its static initializer will throw a headless exception. I verified this under NT and Linux. :(
+<br>
+One good method to troubleshoot is to call the servlet directly: in IE, right-click on the image (presumably missing, otherwise you wouldn't be here...), choose Properties, select the whole path and copy the path into the address line. Call this, and you will get a stack trace detailing the problem. However, it might be necessary to reload the application in between - somehow, only the stack trace of the first call is useful, the next calls to the same servlet will result in a much more generic (bland) error message.
+<br>
+With the method above I was able to use the Cewolf.war files from versions 0.7, 0.8 and 0.8.1. However, only the testpage worked satisfyingly in all cases. The Cewolf set in some circumstances created a<br>
+<pre>
+java.lang.ClassCastException: sun.awt.image.DataBufferNative
+at sun.awt.image.codec.JPEGImangeEncoderImpl.encode(lines 405, called from 228 and 235)
+at de.laures.cewolf.taglib.Renderer.renderLegend(Renderer.java:97)
+at de.laures.cewolf.taglib.LegendTag.doStartTag(LegendTag.java:56)
+at org.apache.jsp.cewolfset_jsp. and so on........
+</pre>
+This is in 0.8.1. In the cewolfset of 0.7, most charts render fine, except for the last two, where it says 'Separate legend befor chart rendering' [sic] and 'Pie Chart with separate legend after chart rendering'. Both charts render fine, but the legends don't. Using above mentioned technique to render the servlet alone (the path is localhost:8080/Cewolf-0.7/cewolf?id=pie&action=renderlegend), the known ClassCastException appears again.
+<br>
+The one thing I still don't get is why my own application does not work on Linux, even though I use the exact same war file on NT without problems. I just get the empty windows, no stack traces in any logs, and calling the servlets alone gets the ClassCastException again, even though I don't think I do anything differently than in the testpage code.
+I just tried to do it under JDK1.4.1_01, but no change (except that the ClassCastException doesn't mention sun.awt.image.DataBufferNative anymore). JDK1.3 might work (I get to see the complete Cewolfset, including the legends), only that I get another error in my DataProvider in a call to Calendar.setTimeInMillis (was protected in 1.3 and is public in 1.4). This error message was what prompted me to switch over to 1.4 in the first place... But I can fix that. Or wait until the casting problem is solved.<br><br></dd>
+<dt><b><a name="Troubleshooting1">2.2. Why does the same chart display again and again even though the data changes?</a></b></dt>
+<dd>A DatasetProducer is supposed to generate the same data when passed in the same paramters. So Cewolf returns a cached instance of a chart if there
+is no change in parameters. If your DatasetProducer produces different data even when parameters do not change you can add a
+fake parameter (e.g. time) to avoid caching.<br>
+Since version 0.9 this issue has been fixed with the new methods in the DatasetProducer interface.<br><br></dd>

+Cewolf can be used inside a Servlet/JSP based web application to embed complex graphical charts of all kinds (e.g. line, pie, bar chart, plots, etc.) into a web page. Therefore it provides a full featured tag library to define all properties of the chart (colors, strokes, legend, etc.). Thus the JSP which embedds the chart is not polluted with any java code. Everything is described with XML conform tags.
+<p>Cewolf is based on <a href="http://www.object-refinery.com/jfreechart/">JFreeChart</a> and uses it's rendering engine to render the final chart image into the clients response stream. No files are created on server side. Everything is based on lightweight session objects and dynamic data analysis. Cewolf consists of one servlet which handles the chart rendering and a taglibrary which translates the chart definition included in the JSP into an HTML img tag which consults the rendering servlet for retrieval of the appropriate chart.

+<h2>Prepare Your Application</h2>
+<p> If you have not downloaded the Cewolf distribution yet, this is the
+point to do it (look at <a
+ href="http://sourceforge.net/project/showfiles.php?group_id=57282"
+ target="new">Download</a>). Put the following JAR files of the <tt>/lib</tt>
+directory into your web application's <tt>/WEB-INF/lib</tt> directory: </p>
+<ul>
+  <li>jfreechart-*-demo.jar</li>
+  <li>jfreechart-*.jar</li>
+  <li>jcommon-*.jar</li>
+  <li>commons-logging.jar</li>
+  <li>cewolf.jar</li>

+  <li>batik-util.jar</li>
+  <li>batik-svggen.jar</li>
+  <li>batik-dom.jar</li>
+  <li>batik-awt-util.jar</li>
+</ul>
+<p> Put the file overlib.js from the <tt>/example</tt> directory into
+your webapps root directory. This file is needed to provide tooltips for
+image maps for Mozilla based browsers. </p>
+<p> That should be all you have to do to prepare your application for
+Cewolf usage. If you encounter any problems in using the Cewolf tags
+(e.g. "No Tags" is displayed in your containers console) you can
+additionally put the <tt>cewolf.tld</tt> (or <tt>cewolf-1.1.tld</tt> for
+JSP 1.1 containers) file from the distribution's <tt>etc</tt> directory
+into a directory of your choice under your web application's root and
+reference this file as the cewolf tag library from your JSPs. </p>

+<h2>Provide a DatasetProducer</h2>
+<p> As Cewolf uses a MVC (Model-View-Control) approach the data which
+are shown in your chart are separated from the view defined in the JSP
+page. So you can change them separately. To provide the chart with the
+correct data you must provide an object which implements the interface<tt>de.laures.cewolf.DatasetProducer</tt>.
+This object is asked to produce data every time a new chart must be
+rendered. Below you can see an example implementation of a
+DatasetProducer which could be used to provide data needed for our
+example scenario. </p>

+<p> As you can see this datasetproducer is not very useful. Normally
+this class would try to access a datasource (e.g. a database) to access
+the needed information. But to serve as an example it should do. </p>
+<p> A DatasetProducer needs to implement three methods. The most
+important one is the <tt>produceDataset()</tt> method which actually
+produces the data which should be used to render a chart. This method
+takes a parameter map which is filled by some special tags of the JSP
+which will be explained later on. </p>
+<p> The <tt>hasExpired()</tt> method is called by the Cewolf framework
+if there already exits a data object produced by this producer in
+Cewolf's data cache. When returning <tt>true</tt> the producer
+signalizes that the data formerly used has expired. </p>
+<p> By providing an unique ID via the <tt>getProducerId()</tt> method
+the Cewolf framework identifies a producer type. Two producer instances
+with the same ID are supposed to produce the same data. </p>
+<p> Compile the class and put it in the correct folder structure under
+your web application's <tt>/WEB-INF/classes</tt> directory to make it
+available for your application. </p>

+<h1>Tutorial: Step 3</h1>
+<h2>Install the Cewolf Servlet in your Web App</h2>
+<p> The rendering of the entire chart is finally provided via a servlet.
+This has to be installed in your web application. Cewolf provides a
+servlet class <tt>de.laures.cewolf.CewolfRenderer</tt> which does the
+job.<br>
+To configure your web application you have to edit the <tt>/WEB-INF/web.xml</tt>
+file. Add the following lines to it:<br>
+</p>
+<pre>&lt;servlet&gt;<br>    &lt;servlet-name&gt;CewolfServlet&lt;/servlet-name&gt;<br>    &lt;servlet-class&gt;de.laures.cewolf.CewolfRenderer&lt;/servlet-class&gt;<br>&lt;/servlet&gt;<br></pre>
+Additionally you should provide a servlet-mapping to tell the container
+which URL maps to your Cewolf rendering servlet.<br>
+<pre>&lt;servlet-mapping&gt;<br>    &lt;servlet-name&gt;CewolfServlet&lt;/servlet-name&gt;<br>  
+  &lt;url-pattern&gt;/cewolf/*&lt;/url-pattern&gt;<br>&lt;/servlet-mapping&gt;<br></pre>
+  
+  You also need to tell CeWolf to load on startup:
+  <pre> &lt;load-on-startup&gt;1&lt;/load-on-startup&gt;</pre>
+To test the correct installation you should start your web app and try
+to call the rendering servlet with a browser (e.g.
+http://localhost:8080/myapp/cewolf?state). Cewolf should answer: "Cewolf
+servlet up and running."
+
+Here is a copy of the example web.xml:
+<pre>&lt;web-app&gt;
+  &lt;servlet&gt;
+    &lt;servlet-name&gt;CewolfServlet&lt;/servlet-name&gt;
+    &lt;servlet-class&gt;de.laures.cewolf.CewolfRenderer&lt;/servlet-class&gt;
+	&lt;!-- sets storage implementation --&gt;
+    &lt;init-param&gt;
+        &lt;param-name&gt;storage&lt;/param-name&gt;
+        &lt;param-value&gt;de.laures.cewolf.storage.TransientSessionStorage&lt;/param-value&gt;
+    &lt;/init-param&gt;
+	&lt;!-- sets overlib.js location relative to webapp --&gt;
+    &lt;init-param&gt;
+        &lt;param-name&gt;overliburl&lt;/param-name&gt;
+        &lt;param-value&gt;etc/overlib.js&lt;/param-value&gt;
+    &lt;/init-param&gt;
+	&lt;!-- turn on or off debugging logging --&gt;
+    &lt;init-param&gt;
+        &lt;param-name&gt;debug&lt;/param-name&gt;
+        &lt;param-value&gt;true&lt;/param-value&gt;
+    &lt;/init-param&gt;
+    &lt;load-on-startup&gt;1&lt;/load-on-startup&gt;
+  &lt;/servlet&gt;
+
+  &lt;servlet-mapping&gt;
+    &lt;servlet-name&gt;CewolfServlet&lt;/servlet-name&gt;
+    &lt;url-pattern&gt;/cewolf/*&lt;/url-pattern&gt;
+  &lt;/servlet-mapping&gt;
+
+  &lt;session-config&gt;
+    &lt;session-timeout&gt;1&lt;/session-timeout&gt;
+  &lt;/session-config&gt;
+
+  &lt;mime-mapping&gt;

+<p> As you can see there are different tags of the cewolf taglib
+involved. The first &lt;cewolf:chart&gt; tag defines a chart with all
+its parameters. The concrete rendering is handled by the
+&lt;cewolf:img&gt; tag which adds the correct &lt;img&gt; tag in the
+rendered HTML page. The connection between both cewolf tags inside the
+JSP is specified by using the same <tt>id</tt> attributes. </p>
+<p> When calling this JSP from a client browser you should see the page
+view statistic chart. If you got a broken image have a look at your
+container's log files. </p>

+<h1>Tutorial: Step 5</h1>
+<h2>Create ImageMap and Tooltip Information</h2>
+<p> To provide your chart with additionnal tooltips and image map
+information you have to provide an additional Java class or enhance an
+existing one like the one below. In this tutorial we will add some
+methods to the datasetproducer class which had been introduced at the
+beginning of this tutorial. </p>
+<p> </p>
+<pre>...<br>  public String generateLink(Object data, int series, Object category) {<br>    return seriesNames[series];<br>  }<br><br>  public String generateToolTip(CategoryDataset arg0, int series, int arg2) {<br>    return seriesNames[series];<br>  }<br>...<br></pre>
+<p> As you can see it is very easy to implement a class that produces
+image map and tooltips information. First of all it has to implement the
+interfaces <tt>CategoryItemLinkGenerator</tt> and <tt>CategoryToolTipGenerator</tt>
+(as it produces a CategoryDataset). For other data types refer to the <a
+ href="../apidoc/index.html">cewolf java api</a>. </p>
+<p> To let your class produce links and tooltips for the chart image you
+have to change the &lt;cewolf:img&gt; tag as follows: </p>
+<p> </p>
+<pre>&lt;cewolf:img chartid="line" renderer="cewolf" width="400" height="300"&gt;<br>    &lt;cewolf:map id="pageViews"/&gt;<br>&lt;/cewolf:img&gt;<br></pre>
+<p> Reload your page and you will see tooltips and links on data points.
+Internet Explorer browsers are handled slightly different as others as
+they are able to render a tooltip based on the <tt>alt</tt> attribute
+inside an image map. All other browser need the overlib.js for this.
+Cewolf tries to determine the used browser and renders a correct page
+transparently. </p>
+<p> For further information on using Cewolf refer to the <a
+ href="../taglib.html">Tag Library Reference</a> and the <a
+ href="../apidoc/index.html">Cewolf JavaDoc</a>. </p>
+<p> <b>If you want to see more examples of how to implement catchy charts
+in your webapp, you should deploy the example webapp (downloadable from
+the <a href="http://cewolf.sf.net" alt="Cewolf Homepage">Cewolf home
+page</a> and have a look at its sourcecode.</b> </p>
