Not only will it be slow, it seems you are not closing them either Well, you are right, I do not close the receiver... Am I supposed to do this? The J2EE1.4 javadoc for the javax.jms.Connection interface indicates: "There is no need to close the sessions, producers, and consumers of a closed connection"... as I close the connection when the client stops, I though it was sufficiant.
