Interrupt an executing method

[Lin Shen]

Hi, I have an object obj, which can be called by other threads to execute a service method, obj.service(). does anybody know how can I abort the execution? So other processes can call obj.service() ?

I do this in RMI. See Tymeac product documentation:
http://coopsoft.com/TyDoc/Cancel.html

It involves using multiple threads and is harder than it looks.

Thread A calls thread B and waits for a reply. Thread B calls service(). If thread B never returns, you can use thread C to notify() thread A that the request is cancelled.

That's basiclly how it works. The implementation is a little more complex.

Call interrupt method.

Sorry, I didnt described it clearly in the last post. What I actually want is to interrupt any other programs that called by Runtime exec method.

This program might run in an infinite loop. So How can I interrupt it from the Java main thread.

Thanks

I don't know how you can "interrupt" that process, if that means you want it to pause and then continue later. If you want to destroy (kill) the process then all you do is this:

Process p = Runtime.getRuntime().exec(.....);
 
// then later...
 
p.destroy();

Thats exactly what I want. I will try that. Thanks
