Bug:
EJBs are listed in the agent view,
but clicking getRemote/getHome in the Bean View
gives me on the console and the debug log:
2002-02-10 17:29:42,093 ERROR
[org.jboss.ejb.EntityContainer] invoke returned an
exception
java.lang.NullPointerException

and of course an "472 MBean failure"
The MBean
[jboss.j2ee:service=EJB,jndiName=ejb/entities/Entity]
throws an MBeanException when calling [getRemote]:
java.lang.NullPointerException
on the page.
A grep on the debug log shows:
server.log.1:2002-02-10 16:48:50,640 DEBUG
[org.jboss.proxy.ejb.ProxyFactory] Bound EntityEB to
ejb/entities/Entity
And I cannot get access to any home interface from the
client. The call does not even reach the server. But
this may be a different story.

With the current optimization hacks around the container,
any client that does not provide an Invocation object which
contains the method call information will fail.
Need to talk to Marc about this.
