Java EE6: EJB3.1 Is a Compelling Evolution
EJB 3.1 is a worthy successor to the work EJB 3.0 started. It provides new support for classic Gang-of-Four style Singletons, CRON-like scheduling, no-interface views and asynchronous methods. EJB 3.1 also includes support for in-.WAR deployment, eschewing the need for .EAR files.

Java EE 6 Web Services: JAX-RS 1.1 Provides Annotation Based REST Support
JavaEE 6 release includes Java API for RESTful Web Services (JAX-RS) support which provides a POJO based framework to build lightweight web services that conform to the Representational State Transfer (REST) style of software architecture. JAX-RS version 1.1, which is part of JSR 311, offers several annotations that can be used to expose Java class methods as web resources.

The Java EE 6 Web Tier: JSF 2 Gains Facelets, Composite Components, Partial State Saving and Ajax
In the second of two articles looking at the Java EE 6 Web Tier we turn our attention to JSF 2.0, looking both at the new features and where the ideas for them came from. JSF 2.0 addresses many complaints about JSF 1.x and adds a large number of new features including Composite Components, Ajax support, Partial State Saving, improved Exception handling and integration with Bean Validation.

Dependency Injection in Java EE 6 Provides Unified EJB and JSF Programming Model
Dependency Injection is one of the main features of recently released Java EE 6 version. JSR 330 (Dependency Injection for Java) provides a standardized and extensible API for dependency injection. And JSR 299 (Contexts and Dependency Injection for the Java EE Platform 1.0), which builds on JSR 330, unifies and simplifies the EJB and JSF programming models.

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. In the first of two articles on the EE 6 web tier InfoQ takes a look at the Servlet 3.0 specification.

Bundle.update: OSGi in Java EE, JSR 294 Marked Inactive
Since the last bundle.update, a number of interesting events have occurred in the OSGi and modular Java space. JSR 294 has been (automatically) marked as inactive, the Enterprise Expert Group has released draft 4, WebSphere will allow direct running of OSGi applications and upcoming OSGi conferences have early bird discounts and call for speakers finishing soon.

Q&A with Gavin King on the Impact of JSR-299 and Weld 1.0 on Java EE and JBoss
As Red Hat ships Weld, Java EE 6's reference implementation for JSR-299 (Contexts and Dependency Injection for Java EE), InfoQ talks to specification lead Gavin King about the impact that JSR-299 will have on Java EE 6 and JBoss' products and platforms.

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?

Dependency Injection harmonized for Java EE 6
Earlier this year, Google and SpringSource announced that they were co-operating on a standard set of annotations to be used for dependency injection which were proposed via JSR-330. These annotations didn't line up with those proposed for JSR-299, which generated controversy that has now been resolved, with JSR-299 adopting the JSR-330 annotations and both moving forward to be part of Java EE 6.

Sun's Disagreement With Apache Overshadows Java 7 Announcement
Sun Microsystems have published an updated schedule for JDK 7 along with a list of the approved features, but the ongoing disagreement with Apache over licensing the Java Compatibility Kit (JCK) for Java SE threatens to overshadow the announcement.

Article: Distributed JBI
Officially, the JBI (Java Business Integration) standard is limited to a single Java Virtual Machine (JVM) instance. In a new article, Sun's Derek Frankforth describes and contrasts the strengths and weaknesses two different styles of setting up a distributed JBI topology using OpenESB, and shows how they complement each other in the end.

Sun's Future and Cloud Computing
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.

Web Beans (JSR-299): Q&A with Specification Lead Gavin King
An ambitious and key part of Java EE 6, the Web Beans specification spans JSF/EJB integration, context management, dependency injection and AOP. The specification is currently in public review and the review period has been extended into 2009. An Alpha build is also available. InfoQ talks to Gavin King to find out more about the state of play of the specification and progress to date.

Servlet 3.0 Public Review Sparks a Debate
JSR-315 has produced a Public Review (PR) of the Servlet 3.0 specification, accompanied by a reference implementation in the GlassFish trunk. This release has resulted in a debate around the choices that the Expert Group (EG) has taken for the next generation Servlet APIs and the whole of the Java EE 6 platform.
