I am using JBOSS 5 CR2. In my application, I am starting my internal job server at the port 1099. Now, JBOSS also uses this port for its Naming service. I changed the port value of this service to 1200 so that it does not conflict with my internal job queue port of 1099. Now, whenever I am sending a webservice request to my web application deployed in JBOSS, the first request is going through perfectly, however, after returning some response to my web service client, JBOSS is automatically restarting. Is it because I changed the JBOSS naming port from 1099 to something else and since I am using the 1099 port from my code internally its conflicting with JBOSS's code?
