    I've done something simililar. I first got the environment variable PATH
    and checked if the application can be found there and stored the path to
    it then. And then i took the code from
    http://groups.google.de/groups?q=runCommandLine(cmd)&hl=de&lr=&ie=UTF-8&oe=UTF-8&selm=38aa326e.0301010815.55aa869e%40posting.google.com&rnum=1
    and modified it a bit. And then you can execute the program with some
    arguments if needed. Of course your web app needs then special
    privileges you get via netscape.security.PrivilegeManager.enablePrivilege(
      "UniversalXPConnect"); This will ask the user if he wants to gain
    these privileges to the web app. But there is a checkbox where you can
    make Mozilla remember this decision, so the user won't be asked every
    time he uses the web app.
