Hi All...
I'm trying to find a reliable way to stop a NetworkServer instance.
It'd be very nice if this class had a stop() method that would
terminate NetworkServer's run() method and free the port. :-)
My Applet launches and starts a NetworkServer object. The problem
occurs if someone reloads the page. The previous instance's Thread
is still running, hogging the port.
I've tried subclassing NetworkServer, and adding a stop() method:
public synchronized void stop() {
Thread.currentThread().stop();
}
That didn't work.
Then I tried adding the following to Java's NetworkServer class:
private boolean stopRequest = false;
final public void stop() {
stopRequest = true;
}
// inside run() changed while( true ) to this...
while ( !stopRequest ) {
This all compiled fine. When I ran it and called NetworkServer's
new stop() method, I got this message:
java.lang.IncompatibleClassChangeException net.NetworkServer: method stop()V not found

Failed to stop: java.lang.IncompatibleClassChangeException: net.NetworkServer: method stop()V not found
Any ideas?
