In the recently completed Java.net poll on Continuous Integration (CI), a majority of voters declared that they don't know what Continuous Integration is. A total of 280 votes were cast in the poll, which ran for two weeks. The exact question and results were: Does your company utilize Continuous Integration (CI) in its software development projects? 30% (85 votes) - Yes 9% (25 votes) - CI...

Over the next few months, I will be running a new advanced TDD/BDD workshop in cities around Australia, including Sydney, Melbourne, Perth, Canberra and Brisbane (I also travel internationally a lot, so if you are interested but not in Australia, get in touch!). Here is the outline of the new course:   Learn TDD/BDD from the author of BDD in Action Test Driven Development (TDD) is an...

One of the first things we did as we began to learn about Java was to create our own library of Java books. Every member of the development team was given the chance (and funding) to build their own collection of books. In time, these book collections became a sort of "comfort blanket" for the developers. In addition to being a valuable source of reference material, these collections act as a...

Atlassian has made some seriously great products, for example the project tracker JIRA. We recently upgraded our rather archaic version of JIRA at Magnolia to the latest and greatest offering. Everyone in the team found something in this upgrade. Some of us were desperate to use GreenHopper, others were looking forward to a better LDAP integration, and my personal favourite was the new REST API...

Cassandra is an open source column oriented nosql database. It was born to solve problems with persistence and high performance. Cassandra has been used by many companies in many industries for a wide variety of use cases. In addition it has a strong and thriving community supporting it. We will be having a special series of events throughout Brazil in the first week of September. Each day...

How did you first get into developing / coding? My first encounter with a computer was in 1987 during a physics class. This particular one (a Commodore C64) went immediately to my Xmas wish list. When I teared away the gift wrapping, I found the datasette broken. A datasette was a tape drive using audio cassettes for storage – without it, there were no chance to play any of the bundled games;...

Java Desktop

According to research, most complex report development work can be simplified by performing the data source computation in advance. For example, find out the clients who bought all products in the given list, and then present the details of these clients. In developing such reports, it is the “computation” part and not the “presentation” part that brings about major difficulties. In which stage...

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,...

Sebastiano Armeli-Battana is the author of the successful 'MVC Applies to JavaScript' eBook. We thought we'd get to know a little more about the author! 1. For someone that’s new to the JavaScript sector, can you explain why they should use MVC? 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...

Acteur is a pattern for pipelining work - a little DI functional goodness for Java. I might have been speaking Swahili when I wrote about Acteur last month. So here's a simple explanation of the design pattern behind it, with a simple sample project.

The Fundamentals of a JavaScript Test Suite by John Resig and Bear Bibeault, authors of Secrets of the JavaScript Ninja As important as a solid testing strategy is for all code, it can be crucial for situations where external factors have the potential to affect the operation of your code, which is exactly the case you're faced with in cross-browser JavaScript development. In this article...

Java Patterns

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...

Java Web Services and XML

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. Step 1. Create a Jersey Library in JDeveloper Download the latest version of jersey-bundle.jar, which at the time of this writing is version 1.17.1. Start...
