Catch exceptions in javax.swing application

Question

I\'m working with javax.swing to make an aplication which generates forms from XML Schema (using JAXFront library) and stores the data filled by the user them i

Answer 1

Simplest version is to set the default uncaught exception handler:

Thread.setDefaultUncaughtExceptionHandler(new Thread.UncaughtExceptionHandler() {
    public void uncaughtException(Thread t, Throwable e) {
        // do something
    }
});

But that catches uncaught exceptions thrown in other parts of the program aswell.

You could however catch only runtime exceptions thrown off the swing event dispatching thread using a proxy (See this page for more information, copied code from there):

class EventQueueProxy extends EventQueue {

    protected void dispatchEvent(AWTEvent newEvent) {
        try {
            super.dispatchEvent(newEvent);
        } catch (Throwable t) {
            // do something more useful than: t.printStackTrace();
        }
    }
}

Now installing it like this:

Toolkit.getDefaultToolkit().getSystemEventQueue().push(new EventQueueProxy());
