Answer Source

The Servlet code seems correct. Provide web.xml entry and Servlet calling URL.

There are two main reasons which cause this error:

1) You do not have a valid doGet() method, when you type the servlet’s path in address bar directly, the web container like Tomcat will try to invoke the doGet() method.

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

2) You made a HTTP post request from a HTML form, but you do not have a doPost() method to handle it. The doGet() can not handle the “Post” request.

public void doPost(HttpServletRequest request, HttpServletResponse response)
throws IOException{
