Tomcat 8 preview

Mark Thomas

Audience level:

Tuesday 5:15 p.m.–6 p.m. in Rhein-Neckar


This session covers the changes in Apache Tomcat 8 introduced by the new WebSocket and updated Servlet, JSP & EL specifications as well as the Tomcat specific changes and new features for version 8.


Apache Tomcat 8 will implement new versions of the Servlet, JSP and EL specifications as well as adding support for the new WebSocket specification. Work is also planned for internal refactoring in a number of areas that will impact 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.
