It's preferable to use a resource-ref for your MDB connection factory : e.g.

@Resource(mappedName="outgoing_factory") QueueConnectionFactory outgoing;

Then acquire a connection only when you want to send a message and close it. The
underlying connection will be pooled so you shouldn't experience significant overhead
in acquiring the connection each time.
