Component implementation classes include your bean implementation classes, like the MDB class or the @Stateless bean implementation class. Those are the ones which have to reside outside of the .ear/lib folder for annotation scanning to take place.

No method to specify to read myproject.jar at .ear\lib foder to find the MDB? It is a bit inconvinent to separate all the MDB class from myproject.jar.

The spec doesn't allow it.

I just copied WorkflowAdditionMDB.class and GenericQueueMDB.class with corresponding folder directories to myproject.ear but there is an error reported when starting JBoss. Thoughts?

Try this in your bean class:

... // the usual annotations
public class WorkflowAdditionMDB extends GenericQueueMDB implements MessageDrivenBean, MessageListener
{
...

Notice that I have explicitly added the implements clause to that bean

[nickarls]

can the messageListenerInterface attribute be applied?

Yes that's the other option.

[honeychen03]

Hi guys, I tried both appending implements clause and messageListenerInterface (messageListenerInterface=MessageListener.class) but neither works for me. Any idea?

[honeychen03]

How do I get to know other options that could be configured here like messageListenerInterface because according to the doc, this attribute is not mentioned? How can I know other attributes? Any example that is fully including the attributes or doc link?

THank you, Nicklas

I packed the mdb classes into a mdb.jar at .ear\mdb.jar but no mdb created when starting jboss. But I just put folders with mdb classes at .ear directory and it worked. The sanning does not support mdb.jar?  Could anybody tell me where could be wrong?

[jaikiran]

Post the output of:

jar -tf mdb.jar

I confirmed that is working when putting com folders at .ear directory.

So is this a bug or something with a packed jar?

[jaikiran]

That should have worked actually.

Try adding this to the .ear/META-INF/application.xml:

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns="http://java.sun.com/xml/ns/javaee"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
        http://java.sun.com/xml/ns/javaee/application_5.xsd"
          version="5">

  <module>
    <ejb>mdb.jar</ejb>
  </module>
</application>
