}
public static boolean isMac() {
    String os = System.getProperty("os.name").toLowerCase();
    return os.indexOf("mac") != -1;
}
public static boolean isLinux() {
    String os = System.getProperty("os.name").toLowerCase();
    return os.indexOf("linux") != -1;
}
public static boolean isWindows9X() {
    String os = System.getProperty("os.name").toLowerCase();
    return os.equals("windows 95") || os.equals("windows 98");

     String subCmd = (exec) ? "exec" : "openURL";
     cmds.add(String.format("kfmclient "+subCmd+" %s", fileName));
  }
  else if (isMac())
  {
     cmds.add(String.format("open %s", fileName));
  }
  else if (isWindows() && isWindows9X())
  {
     cmds.add(String.format("command.com /C start %s", fileName));

  else if (isWindows())
  {
     cmds.add(String.format("cmd /c start %s", fileName));
  }

We do put the command outside somewhere in the configuration file.

Your "JAR and source code" will be "cross-platform", but your deployment doesn't.

You can also do something like this answer. You can put the classname of the factory class of the "Deskop" implementation into the setup file. (may be guide or spring, if you like)
