In Java development, the typical data computation problems are characterized with:
Long computation procedure requiring a great deal of debugging
Data may from database, or Excel/Txt
Data may from multiple databases, instead of just one.
Some computation goals are complex, such as relative position computation, and set-related computation
Just suppose a sales department needs to make statistics...

In report development, we may need to present the data from multiple databases in one report, such as data from MSSQL database for CRM and Oracle database for ERP. If the reporting tool like iReport only supports single data source, then we need to consolidate the multiple data sources into a single data source.
The Crystal, BIRT, and other so-called reporting tools for multiple data source can...

The data computation layer in between the data persistent layer and the application layer is responsible for computing the data from data persistence layer, and returning the result to the application layer. The data computation layer of Java aims to reduce the coupling between these two layers and shift the computational workload from them. The typical computation layer is characterized with...

Recently, I read Why Big Data Projects Fail by Stephen Brobst. I can’t agree more with his opinions which exposed the problem I’ve been worried about. In this article, I am going to further discuss this topic to remind the enterprises to beware of falling into such pitfall of failure.
Let’s have a look on a positive example. As a successful enterprise in leveraging big data, how does Google make...

In Java development, we may encounter the complex set operations. Java alone is not powerful enough to save programmers’ efforts in implementing the computation details, which is time-consuming and poor in code reuse. In view of this, programmers usually resort to dynamic calculation script for set operation.
SQL is surely the first kind of script that comes into most programmers’ mind. However,...

We thought we'd get to know a little more about the author!
I would say that a JS noob should use MVC, just because it’s widely spread pattern used across different programming languages. I think they would enjoy...

Java API for WebSocket is a new JSR to Java EE 7. It provides a stardard Java API for creating WebSocket applications. This gives web applications the ability to push data.
In Java EE 6 samples, we added a chat room sample to illustrate how to use of Servlet 3.0 asynchronous operation. In that sample, the servlet code did the following:
keep track of AsyncContext in a Queue
create a thread to...

This brief blog entry explains the Mojarra bug triage process, and shares some tips for maximizing the chances your bug will be quickly fixed and find its way into a release. Mojarra is the JSF implementation in several app servers and is the source code from which the reference implementation of the JSF specification is derived.
Mojarra has had a publically accessable issue tracker since 2004,...

Expression Language (EL) was first introduced as part of JSTL 1.0, was then moved JSP 2.0 and was unified with JSF 1.2 in JSP 2.1. In Java EE 7, EL is a new separate JSR, JSR 341. Many new features are introduced in EL 3.0.
This blog shows how to use new following new features of EL 3.0:
Lambda expression (section 1.20 of EL 3.0 spec)
The new operator ; to separate...

Most voters in the just-completed Java.net poll on Java EE 7 believe that Java EE 7 will be the most widely used version of Java EE within the next few years. A total of 354 votes were cast in the poll, which ran for three weeks.
The exact question and results were:
How long will it be before Java EE 7 is the most widely used Java EE version?
14% (51 votes) - Less than 6 months

Over the last few years we've been busily writing the latest and greatest version of Magnolia. After all of this focus on new and (we hope) great, it seemed like time to focuse on something old and great.
If you are old enough to remember the ZX Spectrum, the Commodore 64 or their various competitors, or if you like any kind of games, please keep on reading.
You might have heard of the qaop...

Last week, I attended the global live launch of Java EE 7, a webcast I wrote about earlier, titled "Introducing Java EE 7." The live webcast happened twice (on at 17:00 GMT on June 12, and 12 hours later at 05:00 GMT on June 13), thus enabling every Java developer in the world to attend the live session at some point during non-sleeping hours.
The value of attending the live sessions was...

When we started building our first Java application, at my company Amway Corp, many years ago;
we learned our first lesson.
In spite of all the formal training we received, in spite of all the literature at our disposal;
we still needed help with our Java development on a regular basis.
Where would this assistance come from?
At the time, we had no in-house Java subject-matter experts.

Learning Java (or any programming language) can be a great challenge.
Any group of developers, learning Java, will bring with them a variety of backgrounds and experiences.
In our case, our first Java project began with developers that had COBOL language experience.
Our second Java project, began with developers that had RPG language experience.
Even though COBOL and RPG don't "look" like Java,...

An interesting article: Social Enterprise Architecture that describes the idea of using the Social Technologies to improve the engagement and interactions of the business and IT, and the Enterprise Architecture organization to provide more structure and semantics to the interactions and collaboration tools in the enterprise.
There is a tool called Semantic Center that was written in Java and ADF...
