Sorry for the cross-posting (http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3963411#...): It seems no me that just the creators can help me with my Issue :-) I've been searching several JBoss - Source code to find out but I have no clue... I always get a "java.lang.Error: POA: not configured" in my Servlet's service() - method due to a "Address already in use: JVM_Bind" (See mentioned thread for detailed info). What's the reason for this? Which Port is already bound and how to access my IIOP - EJBs from within my WebApp? Any hint is warmly welcome!
