Re: how to execute a class as an external Java application

Arne (and All),
I have written my own version of the method... it's pretty much more
complicated than yours but it seems to me that everything was needed
in order to make it work!

    private static Process startClass(Class cls) {
        String resource = cls.getName().replace(".", "/") + ".class";
        String path = cls.getClassLoader().getResource
(resource).getPath();
        Process process = null;

        int ix = path.lastIndexOf(resource);
        while (ix >= 0) {
            path = path.substring(0, ix);
            if (path.endsWith("!"))
                ix = path.lastIndexOf("!");
            else if (path.endsWith("/"))
                ix = path.lastIndexOf("/");
            else
                ix = -1;
        }
        if (path.startsWith("file:/"))
            path = path.substring(6);
        try {
            process = Runtime.getRuntime().exec("java "
                + ((path.compareTo("") == 0) ? "" : ("-cp " + path + "
"))
                + cls.getName());
        }
        catch (IOException ex) {
            ex.printStackTrace();
            process = null;
        }
        return process;
    }
