Please help.

I can run JBoss 3.2.3 and JBoss 3.2.4RC1 on Window XP.
But I tried to start default JBoss-4.0.0DR2, I got many errors in server.log:

Failed to initialze state from: jboss.rmi:type=RMIClassLoader
java.lang.IllegalArgumentException: Unable to find operation getState()
at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:133)
at org.jboss.mx.server.MBeanServerImpl.invoke(MBeanServerImpl.java:544)
.
.
[org.jboss.management.j2ee.MBean] Failed to initialze state from: jboss.management.local:j2eeType=J2EEDomain,name=Manager
java.lang.IllegalArgumentException: Unable to find operation getState()
at org.jboss.mx.server.AbstractMBeanInvoker.invoke(AbstractMBeanInvoker.java:133)
.
.

These getState() error occured many times.

After JBoss started, I can access jmx-console.

I can run xpetstore application on JBoss 3.2.3 and 3.2.4RC1. But in
JBoss 4.0.0DR2, I copied server/default to server/xpetstore, added files to
support running MySQL, added xpetstore-ejb.ear of xpetstore application,
and started JBoss. But I can't access xpetstore-ejb application.

Has anyone run xpetstore successfully on JBoss-4.0.0DR2?
Are these getState() error causing problem in accessing xpetstore
application?

Thank in advance for your help.
