Apache Tomcat

Apache Tomcat is an open source software implementation of the Java Servlet and JavaServer Pages technologies. The Java Servlet and JavaServer Pages specifications are developed under the Java Community Process.

Apache Tomcat is developed in an open and participatory environment and released under the Apache Software License. Apache Tomcat is intended to be a collaboration of the best-of-breed developers from around the world. We invite you to participate in this open development project.

Apache Tomcat powers numerous large-scale, mission-critical web applications across a diverse range of industries and organizations. Some of these users and their stories are listed on the PoweredBy wiki page.

ApacheCon US 2009, 2-6 November 2009 in Oakland, CA, will have a dedicated track about Tomcat topics. We will celebrate our 10th anniversary as an Apache project, explain the futur developements: Tomcat7, asynchrounous servlets, show how to get the best of Tomcat and how to front-end Tomcat clusters. And the day after we will have a "geek day" where you can get hands-on advice and really join the ranks of the Tomcat initiated!

Join us in Oakland!

For the impatient, current Apache Tomcat production quality releases vs. Servlet/JSP specifications:

Servlet/JSP Spec	Apache Tomcat version
2.5/2.1	6.0.20

To help you determine which release is right for you, the releases are described in more detail.

Please note that although we offer downloads and documentation of older releases we strongly encourage users to use the latest stable version of Apache Tomcat whenever possible. We recognize that upgrading across major versions may not be a trivial task, and some support is still offered on the mailing list for users of old versions. However, because of the community-driven support approach, the older your version the less people would be interested or able to support you. The current status of all Tomcat versions is maintained on the wiki.
