TOMCAT  
Abstract

Apache Jakarta Tomcat is, probably, not named after the Navy's F-14 Tomcat— a supersonic, twin-engine, variable sweep wing, two seats, strike fighter. But, there have a lot in common, except for price. Whereas the F-14 Tomcat costs US$45,000,000, Apache Jakarta Tomcat is free.

Tomcat is open-source implementation of Java Servlet and Java Server Pages technologies developed under the Jakarta project at the Apache Software Foundation. Tomcat is available for commercial use under the ASF license from the Apache web site in both binary and source.

Apache Jakarta Tomcat is a Servlet container which means that Java Servlets can be used   within it to enable programmers to use the Servlet in such things as web pages. Whereas a JSP web page has both HTML and Java JSP code within the same document, a Servlet is a block of code that can be reused. These can then be compiled once and distributed to run on any standards compliant Servlet Container. A Servlet can be called directly to return HTML markup   to a browser, but it is more usual that a JSP page uses the abilities of the Servlet (By calling it methods) and returns a custom representation of the    returned data.
Tomcat is intended to be a collaboration of the best-of-breed developers from around the world.
