I've seen numerous postings regarding ActiveMQ with EJB3, and variations
of a datasource XML file for use with JBoss integration.
However, they don't quite work. Here is what worked for me, it is
actually quite simple:
1. Don't use any datasource file - only the RA file is required. Put it
in the `deploy' directory. The file is called activemq-rar-4.1.1.rar
and it is in the ActiveMQ distribution (lib/optional/)
2. In JBoss, the @ResourceAdapter annotation must be placed on the
Message Driven Bean (MDB). This may vary for other application servers.
3. Examples I've seen elsewhere show an activationConfig with
destination=<a JNDI name for the queue>. This doesn't work. Put the
ActiveMQ destination name in the activationConfig. There is no need to
put the queue in the JNDI.
Here is a working example - for EJB3 on JBoss, no XML descriptors are
needed, just the RA file and the MDB.
import org.jboss.annotation.ejb.ResourceAdapter;
@MessageDriven(activationConfig =
{
@ActivationConfigProperty(propertyName="destinationType",
propertyValue="javax.jms.Queue"),
@ActivationConfigProperty(propertyName="destination",
propertyValue="FOO.TEST"),
@ActivationConfigProperty(propertyName="acknowledgeMode",
propertyValue="Auto-acknowledge")
})
@ResourceAdapter("activemq-rar-4.1.1.rar")
public class TestBean implements MessageListener {
public TestBean() {
}
public void onMessage(Message message) {
}
}
