Tomcat 7 introduces a number of new features and improvements to the open source Java Servlet and JavaServer Pages container. Along with support for Servlet 3.0, JSP 2.2 and EL 2.2, this latest version’s other improvements include support for aliases, memory leak protection, and a cross-site forgery prevention filter.
With Tomcat 7.0.2 having been available in beta for a couple of months, now is as good a time as any to try it out. The last major release (Tomcat 6.0) came out way back in December 2006, with the most recent stable version (6.0.29) coming out in July 2009.
In the ServerWatch article Getting Started With Apache Tomcat 7, Juliet Kemp provides all the information you need to install, use and configure this latest version of Tomcat. She writes:
[Tomcat] 7.0.2 is still in beta, so it’s not a good match for production sites just yet. The Apache Group has specifically recommended against using it for business purposes right now; the changes are large enough that they want some real-world testing before it’s released as production code. However, it’s well worth installing on a non-production server to test it out.
