DoGet method is called 2 times when a switch-case statement is used

Question

Hello all,
I have a servlet that, when run from browser, runs the doGet method 2 times.
I have a switch case statement within the servlet and when I comment out this servlet, it runs 1 time as expected.
Here is the code:
public class RSSServlet extends HttpServlet {
    /** Processes requests for both HTTP <code>GET</code> and <code>POST</code> methods.
     * @param request servlet request
     * @param response servlet response
    protected void processRequest(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        System.out.println("CALLED SERVLET");
        response.setContentType("text/xml;charset=UTF-8");
        PrintWriter out      = response.getWriter();
        DBQueriesRSS queries = new DBQueriesRSS();
        String queryType     = request.getParameter("queryType");
        String strCount      = request.getParameter("count");
        int count            = (strCount != null && !strCount.equalsIgnoreCase("null") && strCount.length() > 0) ?
            Integer.parseInt(strCount) : 25;
         if(queryType != null && !queryType.equalsIgnoreCase("null") && queryType.length() > 0) {
            System.out.println("IN IF STATEMENT");
            switch(Integer.parseInt(queryType)) {
                case 1 : out.println(queries.getDefault(count));System.out.println("1");       break;
                case 11: out.println(queries.getDefault(count));System.out.println("11");       break;
                case 21: out.println(queries.getTopDaily(count));System.out.println("21");      break;
                case 22: out.println(queries.getTopWeekly(count));System.out.println("22");     break;
                case 23: out.println(queries.getTopMonthly(count));System.out.println("23");    break;
                case 24: out.println(queries.getTopYearly(count));System.out.println("24");     break;
                case 31: out.println(queries.getTopNDailyBW(count));System.out.println("31");   break;
                case 32: out.println(queries.getTopNWeeklyBW(count));System.out.println("32");  break;
                case 33: out.println(queries.getTopNMonthlyBW(count));System.out.println("33"); break;
                case 34: out.println(queries.getTopNYearlyBW(count));System.out.println("34");  break;
                default: out.println(queries.getTopWeekly(25));System.out.println("default");    break;
            System.out.println("OUT OF SWITCH");
        System.out.println("OUT OF IF");
        out.close();
    // <editor-fold defaultstate="collapsed" desc="HttpServlet methods. Click on the + sign on the left to edit the code.">
    /** Handles the HTTP <code>GET</code> method.
     * @param request servlet request
     * @param response servlet response
    protected void doGet(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
        processRequest(request, response);
    /** Handles the HTTP <code>POST</code> method.
     * @param request servlet request
     * @param response servlet response
    protected void doPost(HttpServletRequest request, HttpServletResponse response)
    throws ServletException, IOException {
       processRequest(request, response);
    /** Returns a short description of the servlet.
    public String getServletInfo() {
        return "Short description";
    // </editor-fold>
} The results from running this servlet are:
http://localhost/proxy/RSSServlet??queryType=34&count=66
CALLED SERVLET
IN IF STATEMENT
34
OUT OF SWITCH
OUT OF IF
CALLED SERVLET
IN IF STATEMENT
34
OUT OF SWITCH
OUT OF IFAnyone see anything obvious?
TIA!

Answer 1

in your case you want 'count' to be a class attribute rather than a local variable. But yes, incrementing it each time that the method is called will serve your purpose.
