Re: [Wrapper-user] Does Java service wrapper support multithread?

[Justo C. <jca...@cf...>]

Kin,

If you are spawning your threads but then immediately returning control to
your main class and then calling System.exit(...), this could be a reason
why. The code that spawns your threads needs to block until the new threads
are interrupted or complete their work. Only then should you call
System.exit(...). For example....

Thread myThread = new Thread() {
    public void run() {
        // your code
    }
};

myThread.start();
System.exit(...); // ouch !! this would be a problem, since myThread.start()
does not block !!

But I'm only guessing here. Leif is correct, run your program in console
mode and check wrapper.log. If my guess is correct, your program will exit
before your spawned threads can do any useful work.

Thanks - Justo
