A First Look at Tomcat 5

by Daniel H. Steinberg
ONJava Newsletter for 01/29/2004


About a week ago the Tomcat team announced the availability of Tomcat 5.0.18 stable, which followed on the first stable 5.x release last month. Jason Brittain, author of O'Reilly's "Tomcat: The Definitive Guide," has gathered his thoughts on What's New in Tomcat 5. Brittain writes that one goal was to repair the split that "had occurred in the Tomcat community between the Tomcat 3 branch proponents and the Tomcat Catalina developers." He outlines the new Tomcat support for the recently finalized Java Servlet 2.4 and JSP 2.0 Specifications. Tomcat 5 has improved memory management and garbage collection. Other covered enhancements include better support for JMX, an improved build system, and increased JSP tag library efficiency via tag pooling and tag plug-ins.

Denis Piliptchouk returns with part three of his series on Java vs. .NET Security. This time he concludes, "Java provides a solid API for dealing with certificates. .NET programmers have to turn to unmanaged CAPI functions to access certificates, unless they use WSE, which adds a lot of useful functionality." He found no clear winner in cryptographic Code Protection, and only a slight advantage for Java in non-cryptographic Code Protection. Piliptchouk reports, ".NET defines a richer sets-based permission structure than Java. At the same time, .NET permissions reveal their binding to the Windows OS. [..] Policy in .NET has a much more sophisticated structure than in Java, and it also works with many more types of evidences. Java defines a very flexible approach to adding and overriding default policies--something that .NET lacks completely. [.. and] .NET arms developers, with an impressive arsenal of various features for access checks, easily surpasses Java in this respect."

This week's java.net feature is Mike Clark's guide to getting started writing code test as the first step this year. Sure you've read many articles about test-driven development, but Clark shows you how easy it is to get from your current approach to automating your tests. He then pushes you to consider test-first as a design activity. In The Testing Bug, Clark gives you a dozen activities to get started testing first.
