This is going away, at least for the default configuration for 4.0?  I'd rather not have to try to deal with the JMSContainerInvoker

I thought JBoss Messaging was working on just the JMS implementation, not the EJB container and JCA 1.5 adaptor. And if I work on anything it'd be for the new .rar.

I was thinking that the org.jboss.resource.adapter.jms.inflow.DLQHandler had a fairly decent interface.  Perhaps I would do the following:


  | /**
  |  * An interface for inflow message Handling.
  |  */
  | public interface InflowHandler
  | {
  | 
  |    /**
  |     * Set up the handler.
  |     * @throws Exception for any setup failure
  |     */
  |    void setup(JmsActivation activation) throws Exception;
  | 
  |    /**
  |     * Tear down the handler.
  |     */
  |    void teardown();
  | 
  |    /**
  |     * Handles the message, return true if the message should not be further processed.
  |     */
  |    boolean handle(Message msg);
  | 
  |    /**
  |     * Notification that the message was delivered
  |     */
  |    void messageDelivered(Message msg);
  | 
  | }
  | 

I would probably make DLQHandler a subclass of InflowHandler and change the signatures slightly.  The activation parameters would include a list of classes.  What do you think?
