Apache Tomcat is a web container, or application server developed at the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, providing an environment for Java code to run in cooperation with a web server. It adds tools for configuration and management but can also be configured by editing configuration files that are normally XML-formatted. Tomcat includes its own internal HTTP server.

Development status
Members of the ASF and independent volunteers develop and maintain Tomcat. Users have free access to the source code and to the binary form of Tomcat under the Apache License. The initial Tomcat release appeared with versions 3.0.x (previous releases were Sun internal releases, and were not publicly released). Tomcat 6.0.14 is the latest production quality release[1] of the 6.0.x trunk (the branch for the 2.5 servlet specification)[2], 2007.

History
Tomcat started off as a servlet reference implementation by James Duncan Davidson, a software architect at Sun Microsystems. He later helped make the project open source and played a key role in its donation by Sun to the Apache Software Foundation. The Apache Ant software build automation tool was developed as a side-effect of the creation of Tomcat as an open source project.[3] Davidson had initially hoped that the project would become open sourced and, since most open source projects had O'Reilly books associated with them featuring an animal on the cover, he wanted to name the project after an animal.[3] He came up with Tomcat since he reasoned the animal represented something that could fend for itself. Although the tomcat was already in use for another O'Reilly title, his wish to see an animal cover eventually came true when O'Reilly published their Tomcat book with a snow leopard on the cover[4].
