FYI:

I was trying to generate some MBean w/ XDoclet (JMXDoclet). XDoclet generated perfectly!!!

However on deployment I get an error here:

/**
*
* @return
*
* @jmx:managed-operation
*/
public void start() throws Exception {

// Error here:
List list =MBeanServerFactory.findMBeanServer(null);

server = (MBeanServer)list.iterator().next();

timerObj = new Timer();



The error is:

java.lang.NoSuchMethodError: javax.management.MBeanServerFactory.findMBeanServer(Ljava/lang/String;)Ljava/util/List;
at net.discserver.common.util.jmx.TaskScheduler.start(TaskScheduler.java:97)

Wow... Nasty error!!!!!!! Doesn't make any sense.

After a whole day of debugging, the problem was due to the openjmx.jar in $XDOCLET_HOME/lib. So when XDoclet compiled the MBeans, openjmx.jar library was used. JBoss 3.0.x does not seem to be compatible w/ openjmx.jar.

Solution:
Replace openjmx.jar w/ jboss-jmx.jar.

Maybe I did not read the XDoclet properly. But just wanted to share my experience.

Is this the correct solution?

Anyhow, overall very impressed w/ JBoss!!!! And XDoclet!!!

Thanks All!!!
