I'm still working with the DayTrader streamer client and have run
into another issue I cannot explain. Both the streamer and ws app
client create Swing-based GUIs. I am in no way a Swing expert;
however, all of the docs that I have read indicate that the GUI
thread should remain up and running (along with the JVM) after main
completes. Here is an example...
public class JFrameExample {
public static void main(String[] args) {
JFrame f = new JFrame("This is a test");
...
f.addWindowListener(new ExitListener());
f.setVisible(true);
}
}
From what I have seen all Swing apps use some variation of this, as
do the DayTrader streamer and ws app clients.
Unfortunately, when I try to run these clients in under Geronimo
2.0.1, the apps terminate when the main thread completes. I have
added a Thread.sleep() to the main just to verify that the GUI
remains up while the main thread is still active.
Does anyone have any thoughts as to why the JVM is terminating with
main while the GUI threads are still active and have not been
closed? I've tried a SUN and IBM JVM and both result in early
termination. The only thing I can think of is that something in the
Geronimo client or the manner in which Geronimo packages the client
that is changing the behavior.
I remember fixing this once....
My guess is that it got broken again when gianny added the bootstrap
repository. A JIRA would be good I think. I suspect if you look
around at the various command line classes you can see the code that
shuts down the client from a shutdown hook and see why it isn't
getting used.
I'll try to find some time to take a look at this if you don't beat
me to it.
