Hi,

I am trying to send a message to a remote queue deployed on a JBoss as 7.1.1.Final / HornetQ server from a stateless EJB3 on JBoss AS 5.1.

I have tried to use the Alunite class loader as described in this message and here. in order to load jboss-client.jar (from as 7) in an isolated class loader :

            // Loads as 7 client jar with Alunite
            this.loadAS7ClientJar();

              Hashtable< String, String > env = new Hashtable< String, String >();
              env.put(Context.INITIAL_CONTEXT_FACTORY, JNDI_FACTORY);
              env.put(Context.PROVIDER_URL, url);

              // UserName & Password for the Initial Context for JNDI lookup
              // This user should have been created in the JBoss realm
              env.put(Context.SECURITY_PRINCIPAL, user);
              env.put(Context.SECURITY_CREDENTIALS, password);

              as7InitialContext = new InitialContext(env);

              // Lookup the JMS connection factory
              connectionFactory = (ConnectionFactory) as7InitialContext.lookup(JBossAs7JNDIClient.JMS_REMOTE_CONNECTION_FACTORY);

and for class loading :

public void loadAS7ClientJar() throws MalformedURLException
{

String jbossHome = System.getenv("JBOSS_HOME");
  
        if (jbossHome == null)
        {
               jbossHome = System.getProperty("jboss.home");
        }

        if (jbossHome == null)
        {
              throw new IllegalStateException("Neither JBOSS_HOME (env) nor jboss.home (property) is set");
        }

          File as7ClientJar = new File(jbossHome, AS7_CLIENT_JAR);

          LOG.info("Loading {} {}", as7ClientJar.getAbsolutePath(), as7ClientJar.exists());

          URL clientUrl = as7ClientJar.toURI().toURL();

          URL urls[] = { clientUrl };

          // Don't set a parent, so we run in complete isolation.
          URLClassLoader urlCl = new URLClassLoader(urls, null);
          ClassLoader cl = new AluniteClassLoader(urlCl, ClassLoader.getSystemClassLoader());

          Thread.currentThread().setContextClassLoader(cl); 

  }

I get a class cast exception : HornetQJMSConnectionFactory cannot be cast in javax.jms.ConnectionFactory.

What is the proper way to lookup a remote connection factory from AS 5 to AS 7 ?

Why do I get a ClassCastException since the current thread class loader is isolated and having the jboss-client.jar in his path ?

Thanks for your help,

Best regards,

Eric
