Launch multiple java applications from one java application

Question

Let's say that I have Client class with a main method that does something (maybe connecting to class Server).

Is there a way to create a class (let's say ClientLauncher) that launch n clients (n passed as a parameter) as different java applications?

Note that, I do not want these clients to be different threads inside one application. I want to obtain the same effect that I would get by pressing the run button in Eclipse several times (launching different main methods).

I'm not sure why you don't want to run clients using threads, Runtime.getRuntime().exec() can invoke extarnal jars within a class

Process run= Runtime.getRuntime().exec("java -jar jarpath_here");

If you put this in loop you'd have multiple processes.
