Porting EJB 3 MDB from OC4J to WLS

Question

Posting this again since my last post didn't seem to take.
I get the following three deployment error messages when attempting to deploy an application to WebLogic Server 10.3 technical preview. The problem is centered around my deployment of an EJB 3 message driven bean.
1. An error occurred during activation of changes, please see the log for details.
2. Exception preparing module: EJBModule(EngineEjb.jar) Unable to deploy EJB: Requestor from EngineEjb.jar: [EJB:011026]The EJB container failed while creating the java:/comp/env namespace for this EJB deployment. weblogic.deployment.EnvironmentException: [EJB:010176]The resource-env-ref 'jms/demoQueue' declared in the ejb-jar.xml descriptor or annotation has no JNDI name mapped to it.

3. Substituted for missing class [EJB - 11026]The EJB container failed while creating the java:/comp/env namespace for this EJB deployment. weblogic.deployment.EnvironmentException: [EJB:010176]The resource-env-ref 'jms/demoQueue' declared in the ejb-jar.xml descriptor or annotation has no JNDI name mapped to it. The resource-ref must be mapped to a JNDI name using the resource-description element of the weblogic-ejb-jar.xml descriptor or corresponding annotation.
My MDB uses an annotation like the following:
@MessageDriven(mappedName = "jms/demoQueue", name = "MyMDB",
activationConfig =
@ActivationConfigProperty(propertyName = "destinationType",
propertyValue = "javax.jms.Queue")
@ActivationConfigProperty(propertyName = "messageSelector", propertyValue =
"RECIPIENT = 'MyRecipient'")
Earlier, I did create a JMS Module named demoQueue with the following resources:
Name Type JNDI Name
testQueue Queue jms/demoQueue
ConnectionFactory-0 Connection Factory jms/QueueConnectionFactory
Any suggestions to fix the WLS deployment error?
For continuing compatibility with my OC4J deployment, I would like to continue using a connection factory with the following JNDI name "jms/QueueConnectionFactory" shown above.
So I plan to add the following properties to the @MessageDriven annotation above. These are needed to continue working with our OC4J deployment. However, my primary concern is to get this MDB working with WLS. Does this strategy seem reasonable for allowing deployment to both OC4J and WLS?
@ActivationConfigProperty(propertyName = "connectionFactoryJndiName",
propertyValue =
"jms/QueueConnectionFactory") ,
@ActivationConfigProperty(propertyName = "destinationName", propertyValue =
"jms/demoQueue")
Thanks,

Answer 1

Travis, you pose a very good question. If I understand your goal, you would like to use code that compiles and works in OC4J and WLS. For example, you want to use javax.ejb.MessageDriven instead of weblogic.ejbgen.MessageDriven.
Using something like mappedName as it is referred to here allows you specify the JNDI name in WLS if it is not defined elsewhere, but it appears to be specific to the WLS implementation.
I've seen several other questions posed about finding all of the available ActivationConfigProperty name / value pairs and I have been unable to find it myself.
I tried several permutations of annotations, and I can't figure out why something like this would even work, but it does. The mapped name is my JNDI name, but I never specify that it is a javax.jms.Queue or which connection factory to use. How does WLS figure that out?
@MessageDriven(     
     mappedName = "exampleQueue", name = "HelloWorldMDB"
public class HelloWorldMDB implements MessageListener {
     @Override
     @TransactionAttribute(value = javax.ejb.TransactionAttributeType.REQUIRED)
     public void onMessage(Message message) {
          System.out.println( "received message " + message );
}This is a good question for support as the documentation seems to be incomplete here.
