Problem using MBeans

[jotsetung]

hi
i wrote a MBean and i added this MBean to the jboss-service.xml on a jboss 3.2.1. when i start the jboss i get the error message NoClassLoader found for this class. what did i wrong? i wrote a MBean which implements the org.jboss.system.ServiceMBean interface and packed the MBean in a jar which i putted in the lib directory.
any suggestions?

ok, the ClassLoaderProblem is solved... was my fault. but now i get the error: javax.management.InstanceNotFoundException jboss:service=MBeanTest is not registered.
i wrote this jboss:service... in the name tag of the mbean. how could i register my service?
