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