Does Spring JmsTemplate close connections by default?

Question

I wrote a JMS application that runs within a web service in Glassfish (also deployed it in JBoss), I noticed that after I process several messages through a MessageListener MDP, the JMS server runs out of connections!

Tried it with both Apache ActiveMQ and Glassfish internal JMS broker (openMQ?)

Is there a way to check why this is happening? If this is the default behavior of JmsTemplate, what is my alternative for developing JMS producers and consumers the right way?

Thanks!

Answer 1

The spring JMSTemplate will close and create all resources (Connections, Consumers, Producers ..) each time it receives or sends a message. This will be a huge performance bottleneck if you are not using pooled Connections, Sessions, Consumers .... .

Having said that, yes the JMSTemplate should close your connection each time.

Answer 2

Yes, the connection gets closed. See the code of the execute method:

JmsUtils.closeSession(sessionToClose);
ConnectionFactoryUtils.releaseConnection(
    conToClose, getConnectionFactory(), startConnection);
