Hi,
I assume that your post at http://community.jboss.org/thread/153262?tstart=0 http://community.jboss.org/thread/153262?tstart=0 contains further information about your configuration?
Anyway: if you use annotations, you bind the queue to a JNDI name by using the attribute "mappedName" of the "@MessageDriven" annotation.
@MessageDriven(
activationConfig =
{
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue")
},
mappedName = "queue/MessageBeanQueue")
Otherwise, you might do this through ejb-jar.xml. Here it is a property of "activation-config".
I am just wondering why my sample one time uses two different approaches to do this mapping, but both seemed to work ;-)
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar id="ejb-jar_ID" version="3.0" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Best regards
