Hello, I am running JBoss 4.0.2. I have 2 instances of JBoss A & B A has HAJNDI and JMS on it B is A's client. B looks up a queue on A over JNDI using Spring (2.0.5, JmsTemplate) and gets a java.naming.Reference object. It then bombs because it expects a queue. When I try to lookup the same object from a stand-alone java application, I get a reference to SpyQueue and all is well. For what it is worth, I tried to trace the NamingServer. For requests from JBoss, it goes to NamingServer but for request from the stand-alone application, it goes to TreeHead. I am at the end of my rope here. I would really appreciate any help I can get.
