Hi there,
Here is the snipset of the code:

String objName = "jboss.j2ee:module=KTJAR.jar,service=EjbModule";
MBeanInfo mbeanInfo = connection.getMBeanInfo(new ObjectName(objName));
Set mbeans = connection.queryMBeans(new ObjectName(objName), null);
Object attrValue = connection.getAttribute(new ObjectName(objName), "Containers");
if (attrValue instanceof Collection) {
Object[] attrs = ((Collection) attrValue).toArray();
for(int i = 0; i < attrs.length; i++) {
if (attrs instanceof StatelessSessionContainer) {
System.out.println(((StatelessSessionContainer) attrs).getName());
}
}
}

The connection is an instance of MBeanServerConnection and created by RMIAdaptor.
When I execute this code, I always get this exception:
java.io.NotSerializableException: org.jboss.ejb.StatelessSessionContainer
at java.io.ObjectOutputStream.writeObject0(ObjectOutputStream.java:1054)
at java.io.ObjectOutputStream.writeObject(ObjectOutputStream.java:278)
...

Anything I've done wrong? Or this code couldn't be executed at client side?
My purpose is trying to get the StatelessSessionContainer MBean, and use this MBean to get org.jboss.metadata.BeanMetaData, am I wrong by doing this? Is there an easy way to achieve this?

Your help is apprecitated! and thanks in advance,
Yueming
