Running p4 from Commad Prompt

I am calling the java main class through a batch script and my program calls the perforce (p4) sync operation. But when I close the command prompt in the middle of the sync operation, it terminates the java program but not the perforce sync process....Is there a way to terminate both?

I am calling sync operation through Runtime.exec()...

thanks

When you call Runtime.exec(), keep a reference to the Process object that it returns. Then, when your main class is shut down, have a shutdown hook call the destroy() method of that Process.You add a shutdown hook by calling Runtime's addShutdownHook method.

I wrote it like this....and doesn't seem to do the thing. I am pretty sure I am doing something totally wrong here...Can you see the problem?

=========================================

public static void main(String[] args) {

File f;

Process p = null;

try

{

String line;

Runtime run = Runtime.getRuntime();

p = run.exec("p4.exe -c ClientSpec sync -f");

BufferedReader input =

new BufferedReader

(new InputStreamReader(p.getInputStream()));

while ((line = input.readLine()) != null) {

System.out.println(line+"\n");

}

p.waitFor();

try {

if (p.waitFor() != 0) {

System.err.println("exit value = " +

p.exitValue());

}

}

catch (InterruptedException e) {

System.err.println(e);

}

run.addShutdownHook(new Thread());

}

catch(Exception e)

{

System.err.print(e);

}

p.destroy();

========================================

thanks

nvm I got it to working....

For those who require the method

here it is:

final Process p = run.exec("p4.exe -c clientspec sync -f");

Runtime.getRuntime().addShutdownHook(new Thread(new Runnable() {

public void run() {

p.destroy();

}

}));

Thanks for the help DrClap :)
