Automatically Invoke a JSP Page from Within a URL

The user will never know that a .jsp page is actually being used here for login purposes, which can prove to be a valuable security measure.

You simply need to provide a mapping for the file in the <servlet-mapping> tag as below.

<web-app>

<servlet>
        <servlet-name>UserLogin</servlet-name>
        <jsp-file>/login.jsp</jsp-file>
</servlet>

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

</web-app>
