Servlets are programs written in Java that run in conjunction with a web server. Unlike previous attempts to provide the same sort of functionality (CGI, NSAPI, ISAPI, etc.) Java servlets run on most web servers with little or no modification. Since servlets are written in Java, they're generally easier to maintain than programs written in C or perl and are extremely portable between operating systems.
For more information on Java Servlets, look at the Java Servlet pages at Sun Microsystems.
More information can be found at Sun's JavaSoft web site. Many servlet examples come with JRunPro and have been installed onto your web server. We suggest exploring these examples as you familiarize yourself with servlets. The examples are located in this directory and its subdirectories:
