Hi, Jakarta Commons Daemon (http://jakarta.apache.org/commons/daemon) provides support for running "normal" java classes like unix/windows system daemons/services. The class to be deamonized must either implement the Daemon interface or simply implement a few public methods (init, start, stop, destroy). When using the latter, no additional build dependency is necessary. I've refactored SimpleSocketServer to work with Jakarta Commons Daemon. If desired, I'd contribute a patch. Together with an init.d script it's pretty easy to start and stop a SimpleSocketServer. Regards, Stefan
