executing a jar from a WEB APP

what I am looking for is not executing a jar that isgoing to work in my web app but a jar that is a single application by itself, so I try to run it from my web app, I found this but it doesnt seem to work...

Process myProcess= Runtime.getRuntime().exec("java -jar tc.jar");

any ideas pls..

I am using runtime and it doesn't work

Runtime.getRuntime().exec("java -jar "+_request.getRealPath(_request.getContextPath())+"\tc.jar");

nothing there , I tried the following and nothing either

try {

TimerClock.main(new String[0]);

System.out.println("before any error");

} catch(Exception ex) {

System.out.println("the exception is " +ex);

}

Is there anything wrong?

But if you did want to use Runtime#exec(), it would look like:

Process process = Runtime.exec("java -jar foo.jar");

int response = process.waitFor();

if (response != 0) {

throw new RuntimeException("Error executing foo.jar");

}

// Continue

mmm One more issue

when I run this not in java but in windows run

java -jar tc.jar

the equivalents from java is :

TimerClock.main(new String[]{}); ... where TimeClock has the main in tc.jar

What would be the equivalent in java for these two cases

1java mymainclass other.jar(in this case i have to mention the class that has the main : mymainclass )

2 java mymainclass othe.jar -userid="Peter" (in this case it gets a parameter)

Thank you
