RE: openjms0.7.7 / postgres problem

That code snippet doesn't really help identify the problem.

One thing to be aware of - if you have multiple producers/consumers 
created from a single session, only a single thread may access 
any of them at a time. Sessions are single threaded, as per the
JMS specification. The behaviour of multiple threads accessing a 
session (other than the close() method) is undefined.
