It seems you client blocks on the disconnect invocation because there is
no response coming back.

1 .JacORB seems to be in a deadlock - or -
2. xmlBlaster does not respond and your JacOrb client waits forever.

The IDL declaration is:

      void disconnect(in string sessionId, in serverIdl::XmlType qos)
                      raises (serverIdl::XmlBlasterException);

So the client can only expect an XmlBlasterException but never a return
value.

If it continues to be a problem change the IDL to

  oneway  void disconnect(in string sessionId, in serverIdl::XmlType qos);

-> oneway and without an exception.
Please report to us any progress with this issue.
What does the server side logging say?

Do you have a simple example for me to reproduce the problem?

thanks,

Marcel
