ClassLoader issues while typecasting message object of MDB in HornetQ 2.2.5 Final

[surendra.konna]

When i tried to typecast the message object of MDB, i am getting the JMSException as classloader issues.

How can i fix this issue?

I am using  Jboss6-M5.

I tried by commenting WarClassLoaderDeployer in war-deployers-jboss-beans.xml

<!--   <bean name="WarClassLoaderDeployer" class="org.jboss.web.tomcat.service.deployers.WarClassLoaderDeployer">

      <property name="relativeOrder">-1</property>

      <property name="filteredPackages">javax.servlet</property>     

   </bean> -->

and also with onMessage to temporarily change the TCCL.  But both cases are not working.

Even migrating HornetQ from 2.1.2 to 2.2.5 Final is also not working...

=====onMessage() of MDB=========

public void onMessage(Message msg)

{

     try{

          if (msg instanceof ObjectMessage){

               System.out.println(" DEBUG >>>>> ObjectMessage Found for Delivery");

               EmailInfo emailInfo = null;

               emailInfo = (EmailInfo) (((ObjectMessage)msg).getObject());

               try{

                         System.out.println(" DEBUG >>>>> Message Found for Delivery");

                         new SendEmailHelper(emailInfo).sendMail();

                         System.out.println(" DEBUG >>>>> Message Sent using HornetQ");

                }

               catch(Exception e){

                          e.printStackTrace();

                }

          }

     }

     catch (JMSException je)

     {

          System.out.println(" DEBUG >>>>> JMSException>>>");

          je.printStackTrace();

          System.out.println(je.getMessage());

     }

}

First thing: try a later version

[surendra.konna]

I fixed this issue by changining the value to false in ear-deployer-jboss-beans.xml of deploy folder.

<bean name="EARClassLoaderDeployer" class="org.jboss.deployment.EarClassLoaderDeployer">

      <!-- A flag indicating if ear deployments should have their own scoped

         class loader to isolate their classes from other deployments.

      -->     

      <property name="isolated">false</property>

   </bean>

[clebert.suconic]

That means you had some classLoading issue with your project. It's a classic issue.. nothing to do with HornetQ. It's a deployment and configuration issue of your app.

[surendra.konna]

Yes Clebert, I can agree with you..

that is my configuration issue and i am happy to say that i migrated my app from jboss 3.2.8 to jbossAS6 with HornetQ(2.2.14).

Thank you for all of your assistance with quick replies.
