The Rogue Wave® JViews JavaScript Web application support is based on the Java™ servlet technology. Servlets are Java programs that run on a Web server. They act as a middle layer between HTTP requests coming from a Web browser or other HTTP clients such as applications and the application or databases on the Web server. The job of the servlet is to read and interpret HTTP requests coming from an HTTP client program and to generate a resulting document that in most cases is an HTML page.

For more information about servlet technology, you can visit the JavaSoft™ site http://java.sun.com/products/servlet.

A servlet answer HTTP requests from a client and deliver images to this client, as illustrated in the following figure.
