MDB in EJB 3.0 and JBOSS AS 6.1 final

[Abhishek Guru]

Hello,

Any one now how to create an MDB using JBOSS AS 6.1 final and EJB 3.0.

I am using Eclipse IDE 3.5.
Using ant build to create EAR file.

If possible please explain deployment descriptors
ejb-jar.xml, jboss.xml, jboss-web.xml.

Are they still needed in Jboss AS 6.1 final release or we use only Annotations for createing MDB.

I googled a lot but did not find any tutorials that worked for me.



Regards and Thanks
Abhishek

Hi,

sample code :

@MessageDriven(name = "EDMProcessRequestQueueListener", activationConfig = {
@ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
// @ActivationConfigProperty(propertyName = "destination", propertyValue = EDMConstants.QueueDestination_MappedName_EDMProcessRequestQueue),
@ActivationConfigProperty(propertyName = "destination", propertyValue = EDMConstants.QueueDestination_MappedName_EDMProcessRequestQueue),
@ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge") })

public class EDMProcessRequestQueueListener implements MessageListener {

@Override
public void onMessage(Message message) {

Hello,

I have tried an example using tutorial :
http://www.mastertheboss.com/jboss-application-server/327-developing-mdb-with-jboss-as-7.html

But I am stuck on error after deployment. This is not an error, a warning says :

[org.jboss.webservices.integration.deployers.WSEJBAdapterDeployer] Ingoring EJB deployment with null classname: null

Here is the jboss.xml :

<?xml version="1.0" encoding="utf-8"?>
<jboss>

   <enterprise-beans>
      <message-driven>
         <ejb-name>LinkInBean</ejb-name>
         <destination-jndi-name>queue/LinkInQueue</destination-jndi-name>
          
      </message-driven>
   </enterprise-beans>
</jboss>

test-hornetq-jms.xml :

<configuration xmlns="urn:hornetq"
            xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
            xsi:schemaLocation="urn:hornetq /schema/hornetq-jms.xsd">


   <queue name="LinkInQueue">
      <entry name="/queue/LinkInQueue"/>
   </queue>


</configuration>

Try specifying the <ejb-class> element in your jboss.xml to point to the EJB implementation class. Although, I think that webservice error could perhaps be ignored. Not sure why webservice is coming into picture.

Thanks for immediate reply.
I have tried to ad <ejb-class> element in jboss-xml. This is not working as jboss.xml is not parsing this element. error is :

ejb-class not found as a child of message-driven in unordered_sequence: mdb-client-id? configuration-name? security-proxy? resource-adapter-name? local-jndi-name? annotation* timer-persistence? jndi-ref* ior-security-config? mdb-user? ejb-timeout-identity? aop-domain-name? mdb-passwd? depends* destination-jndi-name? mdb-subscription-id? create-destination? method-attributes? activation-config? security-identity? ejb-name? ignore-dependency? jndi-binding-policy? pool-config? security-domain? exception-on-rollback? invoker-bindings? {all descriptionGroup}? {unordered_sequence jndiEnvironmentRefsGroup}?

You are right that webservice error can be ignored.

But after successful deployment, I did not able to send message to my MDB. It just run the code smoothly up to the point where I actually send the message to my MDB. But it never reaches to MDB.

Example tried is here :

If you guys having any of the runnning mdb example in jboss6 and ejb 3.0, please mail me at my gmail id
