Session closed suddenly

Hello all,

I have a problem when publishing a message to a topic. The session
is suddenly closed, which is weird since I'm not closing it.
Is there a timeout on a session after which it is closed after
being idle for x seconds?

Here's the code I'm using to publish a message:

    ObjectMessage message = this.topicSession.createObjectMessage();
    message.setObject(txid);
    this.topicPublisher.publish(message);

Here's the stack trace I'm getting:

javax.jms.IllegalStateException: Cannot perform operation - session has been 
closed
        at org.exolab.jms.client.JmsSession.ensureOpen(JmsSession.java:1010)
        at org.exolab.jms.client.JmsSession.createObjectMessage(JmsSession.java:
278)

Jyrki
