    I think in the servlet2 you have to use the doPost() method and not the doGet() method.

    One of the parameter of the doPost() method is an object of HttpServletRequest. You use this object's getParameter() method to retrieve your desired values.

    In your case it would be something like:
    public void doPost(HttpServletRequest req, HttpServletResponse res) throws Exception{
     String subject = req.getParameter("subject");
     String message = req.getParameter("message");
     //rest of your code
    }
