Ciao,
facendo come mi hai consigliato mi dà nuove eccezioni del tipo

GRAVE: Error initializing endpoint
java.net.SocketException: Unrecognized Windows Sockets error: 0: JVM_Bind

GRAVE: Catalina.start
LifecycleException: Protocol handler initialization failed: java.net.SocketException: Unrecognized Windows Sockets error: 0: JVM_Bind

....mha!
