Tomcat, the Reference Implementation for the JavaTM Servlet 2.2 and JavaServer PagesTM (JSPTM) 1.1 technology, is one of the open source projects Sun is involved in.

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

Releases

Tomcat 5.x is the upcoming major release of Tomcat, and builds on the Tomcat 3.3 and Tomcat 4.1 codebases. The 5.x releases implement the Java Servlet 2.4 and JSP 2.0 specifications.

Tomcat 4.x implements a new servlet container (called Catalina) that is based on completely new architecture. The 4.x releases implement the Java Servlet 2.3 and JSP 1.2 technology specifications.

Tomcat 4.1.x. Tomcat 4.1.8 Beta and Tomcat 4.1.10 Stable are the latest releases. Tomcat 4.1 is a refactoring of Tomcat 4.0.x, and contains significant enhancements, including:

• JavaTM Management extensions (JMXTM) technology-based administration features

• JSP and Struts technology-based administration Web application

• New Coyote connector (HTTP/1.1, AJP 1.3 and JNI support)

• Rewritten Jasper JSP technology page compiler

• Performance and memory efficiency improvements

• Enhanced manager application support for integration with development tools

• Custom Ant tasks to interact with the manager application directly from build.xml scripts

Tomcat 4.0.x: Tomcat 4.0.4 is the current production quality release.

There are several versions of Tomcat 3.x currently available for download:

• Version 3.3 is the current production quality release for the Java Servlet 2.2 and JSP 1.1 technology specifications. Tomcat 3.3 is the latest continuation of the Tomcat 3.x architecture and it is more advanced then 3.2.4, which is the 'old' production quality release.

• Version 3.2.4 is the 'old' production quality release and is now in maintenance only mode.

• Version 3.1.1 is a legacy release.

About Java Servlet Technology

Java Servlet technology provides Web developers with a simple, consistent mechanism for extending the functionality of a Web server and for accessing existing business systems. A servlet can almost be thought of as an applet that runs on the server side -- without a face. Java servlets have made many Web applications possible.

The Proposed Final Draft of the Java Servlet Specification 2.4 is available:

About JSP technology

JSP technology allows Web developers and designers to rapidly develop and easily maintain information-rich, dynamic Web pages that leverage existing business systems. As part of the Java technology family, JSP technology enables rapid development of Web-based applications that are platform independent. JSP technology separates the user interface from content generation, enabling designers to change the overall page layout without altering the underlying dynamic content.

The Proposed Final Draft of JSP 2.0 technologyis now available:
