This
might be real, the CMT to BMT on a stateful requires special treatment in the
container.
Can
you open a bug in bugzilla for me?
marc
I am getting
an exception and would like a little help.
I have a stateful Session
bean which makes use of another stateless session
bean
My client app
uses a AgentSession bean (statefull), and at some point calls
available()
which in tern
calls a router (stateless session bean) function.
Q0)
Am i doing something wrong here?
Q1) Can a statefull session bean contain
an entity bean? as its
statefull(sp) data?
/// From
AgentSessionBean
public void available() throws
RemoteException {
System.out.println("In
AgentSession::available");
if (
this.agent != null )
{
agent.setAvailble();
} else
{
System.out.println("ERROR agent is NULL ????
");
}
// now tell the router
that this agent is available.
Router router = null;
try
{
RouterHome rhome =
(RouterHome)(new
InitialContext()).lookup("Router");
router =
rhome.create();
router.agentAvailable(agent);
System.out.println("WOOT pasted
router.agentAvailable(agent);");
} catch (Exception e )
{
System.out.println( "Exception in agentAvailable " +
e.toString()
);
} finally
{
/**
@todo clean up the mess */
}
}
///// FROM
RouterSessionBean
public void agentAvailable( Agent a )
{
System.out.println("In
agentAvailable" );
}
This is the log from
jBoss..
