The goal of the Apache Tomcat Project is to provide commercial-quality server solutions based on the Java Platform that are developed in an open and cooperative fashion. Tomcat 3.x is an implementation of the Java Servlet 2.2 and JavaServer Pages 1.1 Specifications. Tomcat 4.x is an implementation of the Java Servlet 2.3 and JavaServer Pages 1.2 Specifications, and is a re-implementation of the Tomcat servlet engine from the ground up. The current branch, Tomcat 5.x, is an implementation of the Java Servlet 2.4 and JavaServer Pages 2.0 specifications, with increased attention to scalability, reliability, and management functionality.

Xerces2 is the next generation Apache Xerces-J XML parser. This version of Xerces-J defines the Xerces Native Interface (XNI), and provides a complete, standards compliant reference implementation using XNI. The parser was completely re-designed and re-implemented to be simpler and more modular.
