Jquery ajax请求服务器在实时服务器上返回错误代码405？

Question

以下代码在localhost上运行应用程序时工作正常但在托管在实时服务器上时无效，因为ajax请求返回了错误代码

  

此网址不支持405 HTTP方法get。

我已经发出get请求并在doGet方法中处理此请求，然后当我尝试在实时服务器上运行此代码时出现了什么问题。

注意：仅发布所需的代码js代码

Client side code

 $.ajax({

           type:"GET",
           url:"fetchdata1",
           data:"cat="+cat,
           success:function(data){  

           }           
        });

server side code

protected void doGet(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

      String cat = request.getParameter("cat");
      PrintWriter out= response.getWriter();
      ArrayList<product> p = new ArrayList();

    try {
            con=ConnectionManager.getConnection();
            ps = con.prepareStatement("Select product_id,images.product_name,image_name,company_name,price "
                + "from images,products where images.product_name = products.product_name AND "
                + "category_name = ?");

            ps.setString(1,cat);
            rs=ps.executeQuery(); 
            while(rs.next())
            {
                 product pr =new product();
                 pr.id = rs.getInt("product_id");
                 pr.name = rs.getString("product_name");
                 pr.company =rs.getString("company_name");
                 pr.image = rs.getString("image_name");
                 pr.price = rs.getDouble("price");
                 p.add(pr);        
            }

            String json = new Gson().toJson(p);
            response.setContentType("application/json");
            out.println(json);

        }
