Java EE 6 and GlassFish v3 aim to pave the path for the future by right-sizing the Java EE platform, making it more extensible, and easier to develop on. Key changes include introducing profiles like the Web Profile, pruning unused technologies, embracing open source frameworks, and continuing to improve the annotation-based programming model. GlassFish v3 is the reference implementation of Java EE 6 and includes new features like modular architecture, embeddability, and RESTful monitoring and management interfaces.
Java EE 6 : Paving The Path For The FutureIndicThreads
“The Java EE platform is getting an extreme makeover with the upcoming version ? Java EE 6. It is developed as JSR 316 under the Java Community Process.
The Java EE 6 platform adds more power to the platform and yet make it more flexible so that it can be adopted to different flavors of an application. It breaks the ‘one size fits all’ approach with Profiles and improves on the Java EE 5 developer productivity features. It enables extensibility by embracing open source libraries and frameworks such that they are treated as first class citizens of the platform.
Several new specifications such as Java Server Faces 2.0, Servlet 3.0, Java Persistence API 2.0, and Java Context Dependency Injection 1.0 are included in the platform. All these specifications are implemented in GlassFish v3 that providesa light-weight, modular, and extensible platform for your Web applications.
This session provides an overview of Java EE 6 and GlassFish v3. Using multiple simple-to-understand samples it explains the value proposition provided by Java EE 6. “
