In version 2.2.1, we load the class
com.sun.appserv.server.util.Version and call the String getVersion()
method. This is the method we use

    private static final String GLASSFISH_VERSION_CLASS =
"com.sun.appserv.server.util.Version";
    private static final String GET_VERSION_METHOD = "getVersion";
    private static final String GET_PRODUCT_NAME_METHOD = "getProductName";

    private static final Class[] NULL_PARAMS = (Class[]) null;

    private void loadVersionInformation() throws
ClassNotFoundException, NoSuchMethodException,
        IllegalAccessException, InvocationTargetException {
        Class c =
this.getClass().getClassLoader().loadClass(GLASSFISH_VERSION_CLASS);
        if (c != null) {
            Method m = c.getMethod(GET_VERSION_METHOD, NULL_PARAMS);
            if (m != null) {
                version = (String) m.invoke(NULL_PARAMS);
            }

            m = c.getMethod(GET_PRODUCT_NAME_METHOD, NULL_PARAMS);
            if (m != null) {
                productName = (String) m.invoke(NULL_PARAMS);
            }
        }
    }

Hope this helps,
Ed
