java.lang.NoClassDefFoundError: javax/management/DynamicMBea

[jabberw]

Hi.
Something strange.. I'm trying to run standard OpenMBean example - the one comes with Sun's Jmx_RI<1.2> - SampleOpenMBean.java with freshly dowloaded jboss-3.0.7. I get an error (while another sun's example - SimpleStandard.java - runs fine). It fails with exception stack:
------------
java.lang.NoClassDefFoundError: javax/management/DynamicMBean; - nested throwable: (RuntimeErrorException: instantiating SampleOpenMBean failed: java.lang.NoClassDefFoundError: javax/management/DynamicMBean
Cause: java.lang.NoClassDefFoundError: javax/management/DynamicMBean)
at org.jboss.system.ServiceConfigurator.install(ServiceConfigurator.java:153)
at org.jboss.system.ServiceController.install(ServiceController.java:231)
---------
but from running with java -verbose I see - DynamicMbean class was loaded.
Anybody knows - what's may be a problem?
Sincerely,
thanx ahead.
JabberW.

You are in the wrong forum.

Adrian, hi.
Thanx for an answer - but isn't it the right one? - the question is not a jmx-tutorial related but about the JMX server implementation on JBoss. As I found out this time by playing with the working one - StandardMBean - the bean is loaded by jvm-standard classloader, sun.misc.Launcher$AppClassLoader, and not by the thread-context stored org.jboss.mx.loading.UnifiedClassLoader3 which really has an jboss-jmx.jar in it referred urls. I beleive that JBoss is fine and it's just my installation/mbean definition mistake - but, still, isn't that a right forum to ask? Anf if not - could U say - which one is?
Thanx ahead,
JabberW.
