How to map commonj.work.WorkManager with weblogic 10.3 Work Manager

Question

I am trying to use WorkManagers in Weblogic 10.3. I have defined work managers in weblogic-ejb-jar.xml. I declared a resource reference for commonj.work.WorkManager in ejb-jar.xml with the res-ref-name same as the Work manager defined in weblogic-ejb-jar.xml. Here I am posting the code

MDB

package test;

import javax.annotation.Resource;
import javax.ejb.MessageDriven;
import javax.jms.JMSException;
import javax.jms.Message;
import javax.jms.MessageListener;
import javax.jms.ObjectMessage;
import javax.jms.TextMessage;

import commonj.work.WorkManager;


@MessageDriven(mappedName="TEST_Q", name="MDBWithWorkManager",  activationConfig = {
@javax.ejb.ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue  = "Auto-acknowledge"),
@javax.ejb.ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"),
@javax.ejb.ActivationConfigProperty(propertyName = "transactionType", propertyValue = "Container")
 })
    public class MDBWithWorkManager implements MessageListener {

    @Resource(mappedName="TestWorkManager")
    private WorkManager workManager;
    @Override
    public void onMessage(Message arg0) {
      System.out.println("onMessage() called ");
      System.out.println("workManager : "+workManager);
      if(arg0 instanceof TextMessage){
      TextMessage msg= (TextMessage)arg0;
      try {
        System.out.println("Message received-->"+msg.getText());
      } catch (JMSException e) {    
     e.printStackTrace();
  }
 }


}

    }

Getting the following error while deploying

Thanks in Advance!!!!

Answer 1

Try adding res-ref to the actual jndi name mapping in weblogic-ejb-jar.xml for MDBWithWorkManager

something like this,

    <resource-description>
        <res-ref-name>TestWorkManager</res-ref-name>
        <jndi-name>jndiNameOfTestWorkManager</jndi-name>
    </resource-description>

Answer 2

believe what you need is to define a "map"-element called <dispatch-policy> within your bean def - like:

    <weblogic-enterprise-bean>
  <ejb-name>MDBWithWorkManager</ejb-name>  
</weblogic-enterprise-bean>

change it to:

<weblogic-enterprise-bean>
  <ejb-name>MDBWithWorkManager</ejb-name>
  <dispatch-policy>TestWorkManager</dispatch-policy>  
</weblogic-enterprise-bean>
