Thread: 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

i dont have any ouput as it runs in the background dumps a file on desktop and launches other package. the file is dumped on desktop but then the second package never starts there is no output from programe except the products dumped in files on desktop. when i run in netbeans it all works fine with o probs and second package runs

the problem is with a webdriver not shuting down correcley thinks i have it sorted sorry for lack of details but every [roblem i face is the first time i face it me noob
