Re: [Wrapper-user] Starting Swing application from Linux daemon

[Leif M. <le...@ta...>]

Molde,
Thank you.  The java.awt.headless parameter is very useful when you
need to run Java in an environment where it WILL be headless.  It
makes it possible to do things like generate jpegs etc by telling Java
not to look for the native libraries to do so.

In this case however, Lars is wanting to show a GUI in a Windowing
environment from a Java process running as a daemon.

Thanks for the post.

Cheers,
Leif
