Has anything in clustering changed in Orion148 from Orion145. The instructions at http://www.orionserver.com/docs/http-clustering.html dont work for 148 (works for 145) It seems that the multicasting using MulticastTopicConnection is having issues. The server comes back with not in multicast. OrionServer is trying to join at localhost:9128 (JMS port) when it needs a multicast port. How do I make sure it goes to the right port? I have explicitly coded in the host,port in cluster-config. Now the exceptions are gone but it still doesnt work. Is there something else to configure?
