Shortcuts can be removed by using the Java Web Start Application Manager through the "Application/Remove Shortcut" menu item. For more information, see:
2. It is also possible to launch applications through the command line in Windows, Solaris, and Linux. Unknown applications should not be launched through the command line. Sites may consider renaming the Java Web Start launcher ("javaws.exe" for Windows and "javaws" for Solaris and Linux) to prevent Java Web Start from launching. The launcher can be found at: Windows: C:\Program Files\java\j2re1.4.2\javaws\javaws.exe Solaris (if installed using pkg): /usr/bin/javaws Linux (if installed using rpm): /usr/java/j2re1.4.2/javaws/javaws 5.
