[jboss-user] [JCA/JBoss] - JCA Problem: java.lang.IllegalStateException: Trying to retu

[groovie]

Dear Sirs,

i am developping my very first outbound connector and have 
still a litte problem on closing my connection handle.
Aquireing and use of connection from a pool does work
without any problem. Closing the connection from a
session acutally cause a problem.

I guess i have overseen something.

The runtime environment:
  Operating-System:	Fedora-11 Linux
  JAVA:			Java version: 1.6.0_0,Sun Microsystems Inc.
			Java VM: OpenJDK Server VM 14.0-b15,Sun Microsystems Inc.
			(shipped with this Linux-OS)
  Jboss: 		4.2.3.GA

In order to understand what's going wrong i downloaded JBoss-sourcecode
and followed the debugger. I located the problem in the nested class/method:
org.jboss.resource.connectionmanager.NoTxConnectionManager.NoTxConnectionManager/connectionClosed

      ce.getConnectionHandle());
         }

The ce.getConnectionHandle() expression returns null, that seems to cause the problem.
Therefore i think that i forgot to assign a connectionHandle in my ManagedConnection, cause
ce referes to

    ce = new ConnectionEvent(this, ConnectionEvent.CONNECTION_CLOSED) ;

where this referes to my managed connection and ce Event was created in the 
managedConnection method closeHandle.

Thank you for your help,
Groovy
