DayTrader streamer and web services (Swing) clients terminate unexpectedly
--------------------------------------------------------------------------
Key: GERONIMO-3436
URL: https://issues.apache.org/jira/browse/GERONIMO-3436
Project: Geronimo
Issue Type: Bug
Security Level: public (Regular issues)
Components: application client
Affects Versions: 2.0.x
Reporter: Christopher James Blythe
Description from devlist...
All...
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.
Response from David Jencks...
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.
thanks
