I got the Solution Actually there is need to write each servlet and their URL mapping in web.xml and the way is that

<servlet>
<servlet-name>Login</servlet-name>
<servlet-class>User_Entry</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>Login</servlet-name>
<url-pattern>/servlet/Login</url-pattern>
</servlet-mapping>
