please change method="get" to method="post" in your html code. when you use @WebServlet annotation, web.xml file is really not required. — Govind, Jun 06 '20 at 12:19

In you html code you have mentioned method="get" and in your java class Anjali.java you have written code to accept post request only that's why you are getting 404. As you request types are not matching.

Solution:Please change method="get" ---> method="post"

I hope this will solve your problem.
