new to servlet. File Not found exception.

I have a jsp page from which I want to invoke a servlet. I am using the following code

<form action="/servlet/empServlet" method="post">

I have the configured servlet in web.xml file as give below.

<servlet>

<servlet-name>empServlet</servlet-name>

<servlet-class>com.pd.employees.EmpServlet</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>empServlet</servlet-name>

<url-pattern>/servlet/*</url-pattern>

</servlet-mapping>

When I submit the jsp page, I get "HTTP 404 - File not found" error. Why am I getting this error.

I am using Oracle JDeveloper.
