How can MDB listen a remote queue ?

[Nicolas Taillepied]

Hi all,
I have 2 servers (jboss) running on different computers. I wan't to deploy a Message Driven Bean on one computer which listen a queue located on the other computer.
I've made a lot of tries of configurations but unsuccessfully.
Thanks if you known the response

I do not have exact knowledge of how it works on JBoss, but can vaguely
suggest something. I have done a similar exercise on WebLogic 6.1, to
bind to MQSeries queues. The basic idea is to make the queue 'discoverable'
by the MDB.

First discover the foreign QueueConnectionFactory, Queue, etc., using
appropriate context, and then bind these to the local JNDI. Think you have
to do it in a startup class or a session bean that is loaded prior to your
MDB.

public class StartupEJB implements SessionBean {
 
<snip>
public void ejbCreate() {
Properties foreignProps = new Properties();
foreignProps.put(Context.INITIAL_CONTEXT_FACTORY, ...);
foreignProps.put(Context.PROVIDER_URL, FOREIGN_PROVIDER);
foreignProps.put(Context.SECURITY_PRINCIPAL, ...);
foreignProps.put(Context.SECURITY_CREDENTIALS, ...);
 
Properties localProps = new Properties();
localProps.put(Context.INITIAL_CONTEXT_FACTORY, ...);
localProps.put(Context.PROVIDER_URL, LOCAL_PROVIDER);
localProps.put(Context.SECURITY_PRINCIPAL, ...);
localProps.put(Context.SECURITY_CREDENTIALS, ...);

try {
InitialContext localContext = new InitialContext(localProps);
InitialContext foreignContext = new InitialContext(foreignProps);
/* discover and bind QueueConnectionFactory, Queue, etc., 
Eg: 
Object foreignDest = foreignContext.lookup(queueName);
localContext.bind(queueName, foreignDest);
*/
} catch (NamingException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

}
}

Hope this helps you in someway.

Hi

You can do one thing.
I have done that in my previous project.

You have an option of configuring Foriegn JMS Server in the application server.Configure a foriegn JMS server,connection factories and destinations.
Then from MDB listen those destinations.Automatically ur server handles the request.

So no need to do anything.Appliaction server takes care of that.

I thought this is only in WebLogic 8.1.
Is this available in JBOSS? I thought JBOSS doesn't even Messaging
Bridge...
