Hi, I'm testing our application with JBoss 4.2.0 GA (AIX 5.2 and JDK 1.5.0 IBM) and I have a problem with a socket connection: a class running in the web container (JSP custom tag class) opens a socket to a servlet running in the same container but the connection fails and the client class gets java.net.ConnectException: A remote host refused an attempted connect operation. The same app runs without problems on the same server with JBoss 3.2.1 (and JDK 1.4). I solved the problem changing the application architecture: I replaced the socket connection with a method call and now everything is ok, but I'd like to understand why the local socket connection didn't worked... Any idea? Thanks in advance, Andrea View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4082181#...
