Apache Tomcat Totally Explained

Everything about Apache Tomcat totally explained

| latest_preview_version = | latest_preview_date = | operating_system = Cross-platform | programming_language = Java | genre = Servlet container
HTTP web server | license = Apache License 2.0 | website = http://tomcat.apache.org }} 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 shouldn't 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.

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 6.0.16 is the latest production quality release of the 6.0.x trunk (the branch for the 2.5 servlet specification), as of 2008.

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.
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..
