Here in my job we are having a big problem. We have an application that is divided in two client parts: one accessing the Jboss (Linux) via Browser (TomCat) and the other via Swing. Everything works perfectly... but when nobody access de the server (JBoss) for a medium period of time (in other words a period of inactivity), the Swing program can't access the server generating this error on the Swing (JWS) terminal:
java.rmi.ConnectException: Connection refused to host: 192.168.1.13; nested

A strange fact is that the Browser Client always works perfectly even when the Swing one is not working. Another information: when we are accessing the Swing program in our own internal network, the server redirects to other internal machine that have the JBoss running too. It seams to be a RMI connection problem, but we do not know what it is exactly.
Well, Thank you for the attention.
