Description

This presentation will provide a progress update on the development of Apache Tomcat 8. It will cover the new features in the specifications (Servlet 3.1, JSP 2.3, EL 3.0, WebSocket 1.0) as well as the new Tomcat specific features planned/implemented for Apache Tomcat 8.

Abstract

Apache Tomcat 8 will implement new versions of the Servlet, JSP and EL specifications as well as adding support for the new WebSocket specification. Significant internal refactoring has also taken place with further work planned that has improved / will improve a number of Tomcat specific features. This presentation will provide an overview of the changes and new features introduced by both the updated specifications and the Tomcat specific changes. With the first stable Tomcat 8 release expected towards the middle of 2013 (once the Java EE 7 specifications are finalised) this session will enable attendees to identify the Tomcat 8 features of greatest interest to them and provide them with the information required to start planning their migration to Tomcat 8.
