Hi Adrian, Yes you are right. We were not able to configure RemoteTopic ( to Sun eGate eWays JMS server) from the MDB residing on JBOSS. I haven't seen much info in configuring the remote invokes from JBOSS.Hence we used Session bean to directly calling the remote topics. Even if able to configure the MDB succesfully, i still have DurableSubscriber() with same subscription name. My application( after restart) will get the duplicate subscription name exception and can't proceed further.
