+				a Java technology for monitoring and managing applications or devices;
+				similar to SNMP;
+				managed objects (MBeans) can emit events, can be asked for values (e.g. counters) or an action (method) can be called on them;
+				this native Java technology can be also adapted/translated to other protocols like SNMP or WS/SOAP and integrated with the non-Java world;
+				thanks to this abstraction, the managed object can implement only simple Java interface and don't have to deal with other protocols (which is job of generic adaptors)
