Hi The DEBUG messages was cleared. Now i am getting another problem. that is | java.lang.ClassCastException: org.jnp.interfaces.MarshalledValuePair cannot be cast to javax.jms.QueueConnectionFactory | the code is below, the error showing at the lookup line. | Hashtable params = new Hashtable(); | params.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory"); | params.put(Context.PROVIDER_URL, "localhost:1199"); | params.put(Context.URL_PKG_PREFIXES, "org.jnp.naming:org.jnp.interfaces"); | Context context = new InitialContext(params); | QueueConnectionFactory fac = (QueueConnectionFactory)context.lookup("ConnectionFactory"); Is there any changes required for JBossMQ to JBoss Messaging in the code.
