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,...

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.

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...

Bugs are inevitable. Even after you thought you have finished coding your work, another bug creeps in, making you want to wish the bugs were real tangible objects that you could squish with your bare hands. Being a developer, you should be armed with the right weapons to battle bugs for they come almost all the time. In fact, they are building yet another Death Star. If you don't get vigilant,...

Acceptance Test Driven Development (ATDD) is a method wherein business stakeholders, analysts, testers and developers collectively specify and agree on what needs to be completed in the project. Requirement specifications are set and verified even before actual development starts. This ensures that only those value-adding features are delivered to the business.
Instead of validating after the...

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;...

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...

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.

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...

I was pleased at JavaOne 2012 to have an opportunity to converse with JFrog founder Yoav Landman (@yoavlandman). JFrog, in case you're unfamiliar with the company name, is the inventor of Artifactory, the Java repository management solution that won a 2011 Duke's Choice Award. They also regularly produce cool swag tshirts (see below).
Yoav was very busy at JavaOne 2012, but with advance...

So I haven't posted a blog here since 2009 - and haven't work for Sun or Oracle since early 2010. It's been a wild few years working on a number of things as diverse as giant clouds to control software for cameras which go down oil wells. And I have a new blog at timboudreau.com, naturally using a blog engine I wrote myself (I gave myself a project to learn node.js). Currently I'm architecting...

More than a few days ago a friend pinged me complaining that recent Eclipse release was quite sluggish. Since she had taken my performance tuning seminar she knew exactly how to get and read a GC log but as we all do, she was looking for a second opinion. After looking at the log for a minute it because quite apparent that the default configuration left the IDE starved for memory. After a bit...
