getParameter returns null in the servlet

Question

i am trying to pass a string from my jsp to the servlet via href. I use this

<a href="MyServlet?select=title1"> Title1 </a>

then in the servlet i am trying to get the value of the select with this

String s = request.getParameter("select");

But it returns null. Why is that? Thank you!

EDIT I post the code of the servlet

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        String userOption = request.getAttribute("select");
        System.out.println("Select is:" + userOption);
        //in the console i get: Select is:null

Is your servlet invoked properly? please show url pattern and your servlet method — Prasad Kharkar, Aug 07 '13 at 12:18
are you sure you have put this code in your doGet method? because any link causes doGet method to invoke — Prasad Kharkar, Aug 07 '13 at 12:18
yes the servlet is executed normally. I am trying to get the value inside the: `protected void processRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {` — yaylitzis, Aug 07 '13 at 12:26

That should not be String userOption = request.getAttribute("select");

Please understand that attributes are not parameters

It should be String userOption = request.getParameter("select");
