Should I cache JMS Connections with JBoss AS 7 ?

[Mylos Kathos]

Hello! happy new year to everybody !

I have the following question: I have an EJB application which sends some JMS messages:

@Resource(mappedName = "java:jboss/jms/queue/dlmsQueue")

private Queue queueExample;

@Resource(mappedName = "java:/ConnectionFactory")

private ConnectionFactory cf;

private Connection connection;

public void sendMessage(String msg) {

    connection = cf.createConnection();

        . . . . 

}

The JMS ConnectionFactory and the Queue are injected, however the Connection is created every time. Is this a good pattern or should I cache the Connection object ? (maybe in a @PostConstruct method)

I have read here https://community.jboss.org/wiki/ShouldICacheJMSConnectionsAndJMSSessions that the JCA layer might be able to intercept and cache the call, however I would like to check it somehow.

Any help ?

Thanks

Mylos

You should inject "java:/JmsXA" and then you won't have to worry about caching anything because that connection factory is pooled (i.e. it is a <pooled-connection-factory>).  Check out the messaging doc for AS7 for further discussion of the different kinds of connection factories available.
