Can I run Web Start Apps on a headless (monitor-less) UNIX system?
Headless (monitor-less) UNIX machines usually have no XWindow installed and, therefore, lack a browser. You can start your Web Start apps from the command line. Web Start currently cannot run on headless UNIX systems even if you suppress Web Start’s splash popup using the undocumented javaws.cfg.showSplashScreen false property. What you can do, however, is to run your GUI-less apps with Web Start clones such as OpenJNLP or NetX that support command-line only launching without any download progress or signature GUI popups.
