    Default ShutDownListener question

    hi i wrote a program that forces System.exit(0); but first launches ShutDownListener to run another package java -jar path to file/program2.jar
    and this all works fine however i want to run this programe every 5 hours and am usin cron on ubuntu to do this. but the first programe runs fine and i presume exits as i have all output file from the programe stamped with time and ate so it definitly runs however it doesint launch th second package?? does anyone have any experiance with this an be able to shed some light plan b is to write another schedual for second package but that would be iniffeicent and all soo does anyone kjnow why ShutDownListener might work in netbeans but not from terminal? thaks

    You need to do some troubleshooting. Where exactly is the problem? You've got a few different things happening, so you have to narrow the problem down. Does the first program exit without any Exceptions? Does the ShutDownListener fire? Can you run another process from a normal program instead of a ShutDownListener?

    I'm not sure what you want us to do. You haven't posted an SSCCE for us debug, and you say you can't debug it yourself. That's going to make debugging it pretty hard, don't you think?

    If you can't test the whole application, then you need to create an SSCCE that performs a similar action without any overhead. Can you get that to work?
