How to Map a Servlet Within a Servlet

A Java servlet is an extension to your website, so you can customize a Web app within a user's browser. You must map the servlet within another servlet or in your Web page to trigger the browser to run the program when the user opens the Web page. If the user does not have Java installed or permissions are required, the browser displays a box asking the user to install Java or add required permissions.

Instructions

1. Open your Java servlet editor and open the servlet project that you want to load in your users' browsers.

2. Double-click the HTML file on which the servlet runs. The file opens in your editor, which is where you place the mapping.

3. Add the following code to your file:

   <servlet-mapping>
   <servlet-name>Name</servlet-name>
   <url-pattern>servlet URL</url-pattern>
   </servlet-mapping>

   Replace "Name" with the name of your servlet. Replace "servlet URL" with the URL of the servlet executable.

4. Save the changes and open the HTML file in your browser. The URL mapping automatically loads the servlet. If your browser hasn't been set up, a pop-up window opens confirming that you want to allow the servlet to run on your computer.
