Open window from applet (Bang! Howdy)

Question

I need to open an external window from a Java applet. How can I do it without making the window a child of the applet? I need the window to stay open even when the applet is closed. I know it can be done. Bang! Howdy does exactly what I'm trying to achieve.

Answer 1

It looks like Bang! Howdy has the applet download all necessary files and then launches a seperate process to run the application. If you check out the logs of the Java Console, you'll see a bunch of download statements, and then at the end the call to launch the application.

You may also want to look into Java WebStart, it does much the same thing.
