Java: logo removal or shutdown on Windows and Linux

Question

Is there a way for a Java GUI application to respond to shutdown or logout events other than using JNI? (On Windows, JNI will use WM_QUERYENDSESSION, on Linux?)

The method should allow the program to ask users to save, etc., and then continue the process of logging out.

Answer 1

As far as I know, in Java there is no way to catch system shutdown or logout events.

You can, however, catch when the JVM completes by adding closure to completion .
