Value

I am sending json from servlet to android application , and the following exception occurs : -

 org.json.JSONException: Value <html><head><title>Apache of type java.lang.String cannot be converted to JSONObject

Following is my servlet code , please correct me if anything is wrong here :-

public class LoginCheck extends HttpServlet {

  protected void processRequest(HttpServletRequest request,  HttpServletResponse response)
        throws ServletException, IOException {
    response.setContentType("text/json;charset=UTF-8");
    PrintWriter out = response.getWriter();


    JSONObject obj1 = new JSONObject();

    long uname =Long.parseLong(request.getParameter("mobile"));
    String pwd = request.getParameter("pass");

    try  {
    Connection con = new MyConnection().connect();
    PreparedStatement ps = con.prepareStatement("select * from bmt_user  where mobile_num=? and password=?");
    ps.setLong(1,uname);
    ps.setString(2,pwd);

     ResultSet rs=ps.executeQuery();

        if(rs.next())
       {
            obj1.accumulate("login","Success");
            out.println(obj1.toString());

       }

        else
        {
            obj1.accumulate("login","Fail");
            out.println(obj1.toString());
        }
       out.write(obj1.toString());     
    }catch(Exception e){out.println(e.toString());}
  }


  @Override
  protected void doGet(HttpServletRequest request, HttpServletResponse response)
         throws ServletException, IOException {
     processRequest(request, response);
   }

   @Override
   protected void doPost(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {
     processRequest(request, response);
  }

 }

Plus , when i assign the values to uname and pwd directly , without using request.getParameter() , the servlet runs just fine and returns json i.e

long uname = 48372984;
String pwd = "fabcd"

output -

{"login":"Fail"}
