GUI-less application

[Martin Jensen]

Hi

Here is my problem. I'm currently modifying a program to run without
the GUI. It shall run on a headless system where X is not installed.
When I remove the statement that invokes the GUI, the program just
continues reading statements and exits. The GUI somehow kept the
application running.

I have replaced the GUI-statement with

wait()

Now everything works. The program runs just fine the way I want it.
But the problem is that the only way (I know of) to terminate it, is
to kill it. I would like til to just stop wait()ing and execute the
last statements in the code.

How can I send a notify() signal to the program? Can a seperate
program do this?

I don't think any source should be nessesary since this is a general
question, but the code looks like this:

<code>
public static void main(String[] args) {
MainWindow.inst ance().open();
cleanUpMethod() ;
System.exit(0);
}
</code>
I changed it to
<code>
public static void main(String[] args) {
wait();
cleanUpMethod() ;
System.exit(0);
}
</code>
But cleanUpMethod() and System.exit(0) will never run, 'cause I kill
it to stop it.


Thanks

Re: GUI-less application

To keep your GUI-less program running, you have to create a thread, and put
your wait() in it. Your program will terminate when this thread exits; e.g.
after receiving a remote message. The GUI accomplished this by creating a
main event thread that never exited.
