I have tested it with JBoss 5.0.1 and JBoss 5.1.0. The same behavior occurs.
I have even tested it with Eclipse 3.5, JBoss 5.1.0 and JBoss Tools 3.1.0. The same behavior still occurs.
Either I must live with this error or I change the PC.
Something with my network settings seems to be botched.
Peter, thank you very much for your patience and staying power.
JBoss rocks. Eclipse too.
Did you find a solution to this problem, I am facing the same issue with jboss and eclipse ?
in my case the problem was eclipse proxy;
try to disable it (in General -> NetworkConnections set "direct access to internet")
hope this help
