Deploying EJB 3.0 MDB on Weblogic 10.3

Question

My MDB is as follows:
package test;
import javax.ejb.ActivationConfigProperty;
import javax.ejb.MessageDriven;
import javax.jms.Message;
import javax.jms.MessageListener;
@MessageDriven(mappedName = "mdb01/queue01",
          activationConfig = { @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue") })
public class MDB implements MessageListener {
     public void onMessage(Message message) {
          System.out.println("Received Message: " + message);
While deploying it on WebLogic 10.3 I get the below error:
javax.naming.NameNotFoundException: While trying to lookup 'mdb01.queue01' didn't find subcontext 'mdb01'. Resolved ''; remaining name 'mdb01/queue01'
     at weblogic.jndi.internal.BasicNamingNode.newNameNotFoundException(BasicNamingNode.java:1139)
     at weblogic.jndi.internal.BasicNamingNode.lookupHere(BasicNamingNode.java:247)
     at weblogic.jndi.internal.ServerNamingNode.lookupHere(ServerNamingNode.java:182)
     at weblogic.jndi.internal.BasicNamingNode.lookup(BasicNamingNode.java:206)
     at weblogic.jndi.internal.WLEventContextImpl.lookup(WLEventContextImpl.java:254)
     at weblogic.jndi.internal.WLContextImpl.lookup(WLContextImpl.java:393)
     at javax.naming.InitialContext.lookup(InitialContext.java:392)
Please advise what configurations I should do in WebLogic in order to deploy this MDB.

Answer 1

on WebLogic console, go to the "general" tab of your server's page, and click on "view JNDI tree". there you can see whether your queue has been deployed to the server.
if not there, verify that the queue has been properly targeted. it can be tricky, and I suggest you to use subdeployments.
