[FIXED] getting both HTTP method GET is not supported by this URL and HTTP method POST is not supported by this URL

Issue

Learning some Java Web development here and trying to start my first servlet. But I am getting this error: HTTP method GET is not supported by this URL

description The specified HTTP method is not allowed for the requested resource (HTTP method GET is not supported by this URL).

I am using the 'get' method in my html form and, as you can see I have the doget method implemented. But I'm not sure why I'm getting this error. Could it have something to do with my web.xml?

I tried using the POST method by changing the html method to 'post' and by using the doPost method but I get the equivalent error for it, too. I only did this to test and I don't want to use post.

web.xml:

<web-app 
    xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    version="2.4">
  <servlet>
     <servlet-name>AppleFox</servlet-name>
     <servlet-class>com.AppleFox.web.ProcessQuery</servlet-class>
  </servlet>

  <servlet-mapping>
     <servlet-name>AppleFox</servlet-name>
     <url-pattern>/ProcessQuery.do</url-pattern>
  </servlet-mapping>
</web-app>

Servlet code:

package com.AppleFox.web;

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletResponse;

/**
 * Servlet implementation class ProcessQuery
 */
public class ProcessQuery<HttpServletRequest> extends HttpServlet {
    private static final long serialVersionUID = 1L;

    /**
     * @see HttpServlet#doGet(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();
        String query = ((ServletRequest) request).getParameter("query");

        out.println("Sorry we could find any results for " + query + ".");
    }

    /**
     * @see HttpServlet#doPost(HttpServletRequest request, HttpServletResponse response)
     */
    protected void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
        return;
    }
}

I'm also using the 'get' method in my html form. Don't know why I am getting this error.

Solution

Just change the following line and rearrange the imports and everything should work fine:

Change:

public class ProcessQuery<HttpServletRequest> extends HttpServlet {

to

public class ProcessQuery extends HttpServlet {

change the imports to:

import java.io.IOException;
import java.io.PrintWriter;

import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
