Taking Advantage of Multiple Processor Cores in JEE Applications
Michael Juntao Yuan, and Dave Jaffe have published an article on OnJava.com detailing the process of scaling enterprise Java applications on 64-bit multi-core x86 servers. As chip makers such as AMD and Intel transition from faster megahertz per chip to more cores per chip, performance gains will be harder to achieve for traditional single threaded applications.

InfoQ Article: Java, .NET, but why together?
The Java vs. NET war is over. In this article, Ted Neward looks at how we can leverage the strengths of each together, such as using Microsoft Office to act as a "rich client" to a Java middle-tier service, or building a Windows Presentation Foundation GUI on top of Java POJOs, or even how to execute Java Enterprise/J2EE functionality from within a Windows Workflow host.
