You should try and minimise the amount of connections you create (see JMS1.1 4.3): "Due to the authentication and communication setup done when a Connection is created, a Connection is a relatively heavyweight JMS object. Most clients will do all their messaging with a single Connection. Other more advanced applications may use several Connections. JMS does not architect a reason for using multiple connections (other than when a client acts as a gateway between two different providers); however, there may be operational reasons for doing so." However if you are using a JMS JCA resource adaptor to use JMS, then you should *not* attempt to pool connections yourself. This is because with JCA the "connections" are typically proxies around smart connection references which handle pooling transparently for you.
