Windows won't close; app won't exit

Question

Hi,
After some system admin (on Solaris 2.7) my Swing GUI application won't terminate and the main window won't
close. My code in my main window is:
addWindowListener(new WindowAdapter()
public void windowClosing(WindowEvent e)
System.exit(0);
I have to do 'ps' and 'kill -9 <pid>'. The same behavior occurs w/ the Swing Java tutorial apps; e.g.,
I only added a System.out.println("Window closing event captured") in the ListDemo.java src. WHen I close the
main window, I see this string displayed but the window
doesn't close (or it starts to, goes blank) and the app
doesn't exit.
I'm fairly certain it's an environmental problem, but
am stuck as to what to investigate. If anyone has
seen this behavior and could shed some light, I'd be
appreciative...
Thanks,
Marcia

Answer 1

I tried doing this: In the tutorial's ListDemo.java src, I replaced the entire WindowAdapter() code block with one line:
     frame.setDefaultCloseOperation(frame.EXIT_ON_CLOSE);
This didn't help (w/ either JDK 1.4.0 or JDK 1.4.1, on
Solaris). The app still doesn't terminate. The xterm from which I launched the app isn't responding to control-C. I have to kill the xterm. Also, if I can't write a WindowAdapter, how can I do some other stuff
(like closing network connections, etc.) before exiting?
Thanks for the help; any further suggestions would be welcome.
