Nigel, what do you mean by :
"The application must obtain an instance of the JMS listener bean using
dependency injection"
In your examples, it looks like a CDI bean cannot start listening if not
injected :
@WebServlet("/myjmsservlet1")
public class MyJMSServlet1 extends HttpServlet {
*@Inject MyDepScopeListenerBean* myDepScopeListenerBean;
public void service(ServletRequest req, ServletResponse res) throws
IOException, ServletException {
...
}
}
Did I understand well ? Is this the case ? Just like a MDB, I would like a
CDI bean to start listening to a message without being injected, as soon as
the application starts. Something like :
*@ApplicationScoped*
public class MyListenerBean{
@JMSListener(lookup="java:global/java:global/Trades",type=JMSListener.Type.TOPIC
)
public void deliver(Message message) {
...
}
}
Or if we manage to get the @Startup annotation to Commons Annotation :
*@Startup*
public class MyListenerBean{
@JMSListener(lookup="java:global/java:global/Trades",type=JMSListener.Type.TOPIC
)
public void deliver(Message message) {
...
}
}
Just thinking here

Over in the JMS 2.1 expert group I've just published some
proposals to
allow any CDI managed bean in a Java EE
application to listen for JMS messages. This would be implemented as a
standard CDI portable extension and would become
a mandatory part of a full Java EE 8 application server.
I would welcome any comments from the CDI spec experts here. If you're
interested in helping, please take a look at
https://java.net/projects/jms-spec/pages/CDIBeansAsJMSListeners
and send comments or questions to me or to the public
users(a)jms-spec.java.net alias.
Thanks,
