"Program Files" is a Windows directory that you won't find on Linux or Solaris. One normally distributes the jars that a jar depends on in a directory 'close' to the jar's directory. For example myProgram.jar lib/derby.jar lib/library.jar lib/jdom.jar then the class path entry in myProgram.jar will be Class-Path: lib/derby.jar lib/library.jar lib/jdom.jar This class path will be platform independent. |
