Hi Tim, Sorry to disturb you again and again. In fact, I think that my checkout/update issue is due to a specific cvs server port : 2402. Because of AIX. So, you already guess the next question: How to configure jCVS servlet to use this port number rather than the default one? (something like "jcvsii.portNum.pserver.default=2402" into default.properties) Best Regards, Phil
