MDB and Seam lifecycle issues

[viniciuscarvalho.viniciusccarvalho.gmail.com]

Hello there! I know theres an issue for this : https://jira.jboss.org/jira/browse/JBSEAM-2286, but has anyone succeeded in using MDB as Seam components and having it ready (by that I mean with all dependencies injected) if the queue already have messages on it?

When I start receiving messages Seam did not inject components inside my class, So I get an error complaining about trying to use a component outside the context :(

I tried to setup my component by using @Create and setting it as the listener for the queue:

@Create
public void setup(){
@Create
     public void setup() throws Exception{
          InitialContext ctx = new InitialContext();
          Destination destination = (Destination)ctx.lookup("queue/myQueue");
          consumer = queueSession.createConsumer(destination);
          
          consumer.setMessageListener(this);
     }
}

I know it was a naive approach, since the listener would be called outside the seam scope :(, but was a try :(

What I don't get is, why can't seam have a Listener type component? So by just using @Listener for instance on my component it would be managed by seam.

I solved the problem in a very ugly and shameful way (created an internal class and passed all the dependencies I needed to it on the constructor), is there a better way to deal with that?

You can make your MDB a seam component and add a (JBoss-specific) dependency on some JMX bean that starts after seam. I have it working using

@MessageDriven(<as usual>)
@Depends("jboss.j2ee:service=EARDeployment,url='my.ear'")
@Name("mdb")
public void MDB implements MessageListener {
   ...
}

There are some other unusual things in that bean, but I don't remember if that was relevant to the message-receiving or not. If this doesn't work, please let me know and I'll give you more detail.

It does not work under JBoss 5.1GA

Bummer - I was looking to do the same next week. Do you get errors or it just doesn't work?

Can you be more specific about this ?

What exactly do you define in @Depends(..) ? -To which ear do you depend on ? To your own ear ?

I'm having the same problem as Vinicius Carvalho and I'm using Seam 2.2.1 final and JBoss 5.1GA.
