The Java EE 6 Web Tier: Servlets Gain Asynchronous Support, Improved Extensibility
Some of the most significant enhancements in Java EE 6 have occurred in the web tier. The Servlet API, the basis of almost all Java web frameworks, sees improvements to extensibility and plugability, and gains standardised asynchronous support.

Can the Simple Module System save JSR294?
Over the past month there has been a lot of debate on the current state of the Java Modularity working group (JSR 294). Although the JSR tries to find common ground between different module systems (notably Sun's Project Jigsaw and OSGi), the current set of proposals are overly complex and introduce the world's first concept of a meta-module system. Can the Simple Module System save JSR294?

Sun's recent layoffs (which are said to be affecting people working on OpenJDK, the JCP, J2SE, and desktop Java), and also Sun's recent acquisition of cloud infrastructure vendor Q-Layer, keeps alive the question of how Sun will redefine its strategic direction and choose which of its many technology possibilities it will focus upon.
