At 2014/01/11, A big Java EE 7 event has been held on China Nanjing Software Valley jointly organized by China (Nanjing) Software Valley Joint Management Committee and China Nanjing Java User Group.
Beyond being merely a computer programming language, Java is the most widely used software platform in the entire world. There is a large number of various software solutions that were developed using this technology. Without many people being aware, Java is present in our daily lives in embedded technologies like blue-ray discs and a countless number of sites on the internet that...
I describe new subscription/unsubscription processes for firstname.lastname@example.org.
As it seems, Marc and Paul (the leaders of JAX-RS / Jersey) really have understood what OpenSource really means: Communicate with the community, understand their needs and thoughts, accept their ideas. I would wish that more project leaders would assimilate this open mind and welcoming kind of leadership.
In this blog entry I outline the steps necessary to deploy JAX-RS (JSR 311) RESTful web services to the Oracle Cloud. We'll be using Jersey, which is the reference implementation for JAX-RS, and JDeveloper, which is my primary Java IDE.
Servlet 3.1 (JSR 340) is almost ready for the release. One of the new features is the support for non-blocking IO. ReadListener and WriteListener are introduced to allow non-blocking processing in Servlet.
Non-blocking IO can only be used in async (defined in Servlet 3.0) or the upgrade mode. We can set the async in a servlet with @WebServlet annotation.
In this blog, we will illustrate the use...
classes are dead, long live to lambdas
This blog entry brings to your
attention a few points about using these artifacts, as well as
introducing a simple archetype that the Mojarra team uses to facilitate
the creation of automated regression tests.
JSON JSR(pre JCP filed draft)
As announced earlier, Oracle wants to include a Java API for JSON in the Java EE platform. I have circulated the Java API for JSON JSR draft internally in Oracle. If you have any feedback, let me know. I will also reach out to few people(who worked on Java implementations for JSON) to support this JSR. The planned scope for this API is:
Produce and consume JSON...
In which our hero makes Jersey dance in ways that probably make the Jersey authors take to their sick beds with a headache.

There is much discussion these days about HATEOAS (Hypermedia as the engine of application state) so it gets time to clearly say what HATEOAS actually means.
As you can see on the JSR page for JSR-314, the Final Approval Ballot phase for JSF 2.0 is underway and runs til 26 May.
I describe a process used to reduce the number of unknown unknowns remaining in the development for JSF 2.0.
Based on the results of the last-completed Java.net poll, this year's JavaOne in San Francisco, CA is going to be a huge success. Of course, Java.net polls aren't scientific, but it's still surprising when developers overwhelmingly select a single option in a poll. A total of 2146 votes were cast...
Welcome java 7 part 3 -NIO 2 JSR 203
So like the coin project, in the NIO 2 there aren't unprecedented features in this e -specification, but now it's possible do some easier work I/Os in java. With the class java.io.Files are possible to perform several operations in simple mode. For that it needs and uses the java.io.file.Path, this interface represents files and...
The www.abelski.com web site offers free (for personal and academic usage) courses about various topics in software development. The site focuses on Java technologies.
I decided to write down the answer for some questions which my book's readers email me or ask me via twitter in my weblog so everyone can benefit from the answers. Here is the answer to the first question which involves custom security realms.
GlassFish supports 5 types of security realms out of the box which are sd follow:
File Realm: Usefull for development and testing purposes. GlassFish...
A lot of applications these days title themselves RESTful. But how much REST is needed to be RESTful?
