<h1>Tutorial: Step 3</h1> |
| franta-hg@1 | 11 |
<h2>Install the Cewolf Servlet in your Web App</h2> |
| franta-hg@1 | 12 |
<p> The rendering of the entire chart is finally provided via a servlet. |
| franta-hg@1 | 13 |
This has to be installed in your web application. Cewolf provides a |
| franta-hg@1 | 14 |
servlet class <tt>de.laures.cewolf.CewolfRenderer</tt> which does the |
| franta-hg@1 | 15 |
job.<br> |
| franta-hg@1 | 16 |
To configure your web application you have to edit the <tt>/WEB-INF/web.xml</tt> |
| franta-hg@1 | 17 |
file. Add the following lines to it:<br> |
| franta-hg@1 | 18 |
</p> |
| franta-hg@1 | 19 |
<pre><servlet><br> <servlet-name>CewolfServlet</servlet-name><br> <servlet-class>de.laures.cewolf.CewolfRenderer</servlet-class><br></servlet><br></pre> |
| franta-hg@1 | 20 |
Additionally you should provide a servlet-mapping to tell the container |
| franta-hg@1 | 21 |
which URL maps to your Cewolf rendering servlet.<br> |
| franta-hg@1 | 22 |
<pre><servlet-mapping><br> <servlet-name>CewolfServlet</servlet-name><br> |
| franta-hg@1 | 23 |
<url-pattern>/cewolf/*</url-pattern><br></servlet-mapping><br></pre> |
| franta-hg@1 | 24 |
|
| franta-hg@1 | 25 |
You also need to tell CeWolf to load on startup: |
| franta-hg@1 | 26 |
<pre> <load-on-startup>1</load-on-startup></pre> |
| franta-hg@1 | 27 |
To test the correct installation you should start your web app and try |
| franta-hg@1 | 28 |
to call the rendering servlet with a browser (e.g. |
| franta-hg@1 | 29 |
http://localhost:8080/myapp/cewolf?state). Cewolf should answer: "Cewolf |
| franta-hg@1 | 30 |
servlet up and running." |
| franta-hg@1 | 31 |
|
| franta-hg@1 | 32 |
