in the corresponding mdb.ear i changed jboss.xml

client code is in default instance

Properties env = new Properties();
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
env.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
env.put(Context.PROVIDER_URL, "172.16.7.12:1099");

Context remoteCtx = new InitialContext(env);
Queue queue = (Queue)remoteCtx.lookup("queue/testQueue");
QueueConnectionFactory queueFactory = (QueueConnectionFactory)remoteCtx.lookup("java:JmsXA");

I am getting JmsXA not bound exception(what is the right way of look up ?)

when i changed from JmsXA to java:/XAConnectionFactory i am getting queueFactory but i am getting below exception.

javax.jms.InvalidDestinationException: Destination is not an instance of SpyDestination JBossQueue[testQueue]
