HTTP 404 Java Servlets

Question

I get this error when I click on submit

HTTP Status 404 - /GradeRetrieval/DbConnection
type Status report
message /GradeRetrieval/DbConnection
description The requested resource is not available.

This is the form tag, my HTML form has a submit button.

<form action="../DbConnection" method="post">

This is my directory structure

This is my webxml file

<?xml version="1.0" encoding="UTF-8"?>

<servlet-mapping>

I can't seem to figure out what is wrong. Kindly help.

IIRC, the servlet name needs to be fully specified:

<servlet-class>action.DbConnection</servlet-class>

Also, make sure your url-pattern is correct.
