I've not heard of a portable way of doing this.

On Windows for example you can prevent activation of the screen saver by
refraining from passing a WM_SYSCOMMAND message with the wParam parameter
set to the SC_SCREENSAVE value through to the DefWindowProc function, ie
when this message appears you just silently discard it.

Thanks for your fast reply, but I don't understand how I can refrain the
program from passing a WM_SYSCOMMAND message.

Could you explain it in java code?

Haven't a clue, sorry. I would expect it can't be done at all in Java code -
if I were doing it I'd probably look into writing a Windows message hook in
a proper language, putting that into a DLL, and then working out how to
inject that into the JVM's process. However surely someone somewhere must
have already done this! - if you're really lucky you've now got enough
keywords to search for it.

Eg. Make a Win32 C++ app and access it through Java JNI.

It sometimes just happens.
I'm sure i've read this before in de.comp.lang.java - with the same
replies!!!
