Apache Tomcat 7.0, the latest version of the popular open source Java Web server, is available Tuesday from the Apache Software Foundation.
The upgrade constitutes the first major release of the project since 2006. To ease Web framework integration, version 7.0 implements the Java Servlet 3.0, JavaServer Pages 2.2 and Expression Language 2.2 specifications.
Big changes are the support of Servlet 3.0, JSP 2.2, and EL 2.2, but from what I've read there are lots of nice fixes and performance improvements as well. I'm about to set up two new servers so this is great timing!
