I'm running a program from within java using

  p = Runtime.getRuntime().exec(cmd, null, cwd);

I want to kill(close) this program. I tried to destroy the process. tried to make a class that extends Thread and ran that command from its run() & tried to destroy this thread. but Thread.destroy() is NOT IMPLEMENTED as Java doc says !!!!!!!!!!!!!!.

   so, i tried to interrupt this thread but nothing happens also.

  I searched JDC at sun but got nothing. CAN ANY ONE HELP ME PLZ?!!!!!!!
thanks

you start new PROCESS (which is native OS Process), not Thread.

processes may be quite tricky

have you tried process.destroy() ?
what OS/JDK are you using ?

I tried process.destroy() but nothing happened, that is what made try the thread thing.

1. did you read this bug report
http://developer.java.sun.com/developer/bugParade/bugs/4073195.html

2. the only thing that I can suggest is to start some other native process that is going to kill the first one (using kill() or whatever)

try making two shell scripts
first one will start your process / save pid, etc.
second one will kill that process, childs etc.

if you can create such scripts, you'll probably be able to start them from Java ...

re leaving - well, I'm back at the moment :)
