How do i get rid of: HTTP Status 405 - HTTP method GET is not supported by this URL?

Question

I have been breaking my head over this issue over the past few hours. This is my first attempt at writing a web app and deploying it to the apache tomcat web container. I follow a simple tutorial from here and then end up getting this error. Tried a few solutions as appear in other posts about the same issue but none seemed to have worked so far. I am pasting snippets of and web.xml, website.xml and my code files respectively. Kindly see if i am doing something wrong. Thanks in advance.

web.xml:

<?xml version="1.0"?>
<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 
        http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
     version="2.4">
   <servlet>
      <servlet-name>home</servlet-name>
      <servlet-class>website.web.TestServlet</servlet-class>
   </servlet>
   <servlet-mapping>
      <servlet-name>home</servlet-name>
      <url-pattern>/home</url-pattern>
   </servlet-mapping>
</web-app>

website.xml:

<Context path="/website" docBase="C:\Users\Priyankar\workspace\website\web" />

HomeServlet.java

package website.web;

import java.io.IOException;
import java.io.PrintWriter;
import javax.servlet.ServletException;
import javax.servlet.ServletRequest;
import javax.servlet.ServletResponse;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

public class HomeServlet extends HttpServlet {

    @Override
    protected void doGet(HttpServletRequest req, HttpServletResponse resp) 
               throws ServletException, IOException {
                  PrintWriter writer = resp.getWriter();
                  writer.println("<h1>Hello, World!</h1>");
               }        
}

The following is what i see in localhost_access_log:

0:0:0:0:0:0:0:1 - admin [21/Jun/2013:13:25:40 -0500] "POST /manager/html/deploy?org.apache.catalina.filters.CSRF_NONCE=435C56002971030D163AA1C798F91722 HTTP/1.1" 200 14076
0:0:0:0:0:0:0:1 - - [21/Jun/2013:13:28:50 -0500] "GET /website/home HTTP/1.1" 405 1065

manager_log:

The rest appear to be normal to me unless you wanted to have a look at any specific log file.

Here's the screen shot of the project tree from the package explorer:

Answer 1

The class name you gave is TestServlet and your web.xml is HomeServlet. So when you hit the URL it cannot find anything that is called HomeServlet.

Slightly off topic but relevant: You would have caught this during deploying itself if you had the

<load-on-startup>0</load-on-startup>

tag.

That basically loads the Servlet during deploy and if it didn't find any it will throw up. If you don't give that tag, the server loads whenever it feels like.

Answer 2

The code in your screenshot is for a Java class called website.web.TestServlet but your web.xml and code posted say website.web.HomeServlet.
