Apache Tomcat is a Servlet container developed at the Apache Software Foundation (ASF). Tomcat implements the Java Servlet and the JavaServer Pages (JSP) specifications from Sun Microsystems, and provides a "pure Java" HTTP web server environment for Java code to run. Tomcat should not be confused with the Apache web server, which is a C implementation of a HTTP web server; these two HTTP web servers are not bundled together. Apache Tomcat includes tools for configuration and management, but can also be configured by editing configuration files that are normally XML-formatted.

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] In computing, a reference implementation (or, infrequently, sample implementation) is a software example of a standard for use in helping others implement their own versions of the standard. ... James Duncan Davidson, born July 29th, 1970 in Lubbock Texas, raised in Oklahoma and Texas. ... Open source refers to projects that are open to the public and which draw on other projects that are freely available to the general public. ... Apache Ant is a software tool for automating software build processes. ...

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]. Programming Perl is a classic OReilly book. ...
