Test Driven Development (TDD) has become a cornerstone of modern software craftsmanship. Behaviour Driven Development (BDD) takes it to the next level; it provides easier to use and a more readable syntax as well as many other improvements. If you haven't used Test Driven Development before, start with BDD, you will reap the benefits much faster. This book is a hands-on introduction on BDD. Using...

Java User Groups

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,...

Tuning Java code presents many challenges and addresses several goals. One of these goals is to make the application "run faster". Recently, our end-users were getting multiple-second response times from our web application's home page. This was unacceptable. We were asked to see what we can do to make the web application "run faster". We began by looking at the usual suspects... database access...

One of the biggest challenges facing us during the creation of our first Java application was learning to develop with the Java programming language. We were concerned about how well our team of developers would learn and adapt to Java. Since Java was an object-oriented programming language, we had object-oriented concepts to learn as well. Our first Java training class was titled, "Developing...

Assembling a team of Java developers can be a challenging task. Getting the right people together requires a combination of luck, skill, and plenty of patience. When someone new joins your team, they could also be new to your company. Over the years, we have conducted many job interviews of Java developer candidates wishing to join our team and company. Our Java job interview format is simple and...

Our team of Java developers consists of people with various backgrounds and skill levels. Everyone has a role and is assigned tasks based on that role. Team members are expected to know basic programming concepts, core Java and core J2EE. In addition; database access, web-browser, client/server concepts are required as well. It didn't take long for our team to realize there was a lot more to know...

Hello all. I am back with more stories about our adventures in the world of Java. From the distant past to recent events. I hope to entertain, enlighten, and encourage. So hold on to your hats. For software developers in IT, there are times when you find yourself present at the birth of a major application. Normally these are dream assignments. But consider the following additional factors. 1)...

Spatial reference system: What is it? by Regina O. Obe and Leo S. Hsu, authors of PostGIS in Action, Second Edition The topic of spatial reference systems (SRS) is one of the more abstruse in GIS to understand. This is mainly due to the loose way in which people use the term spatial reference system and secondly to its unglamorous nature compared to other areas of GIS. If GIS is Disneyland,...

10 years ago, we began our journey into the world of Java and "J2EE". It was a big risk for my company, Amway Corp, to do this. We had no in-house expertise and we had critical applications to migrate to the new technology. From the beginning, we were determined to succeed. Today, 10 years after; I can say our Java adventure has been very successful. We have created two complex applications and...

A few years ago, we met with our business analysts to discuss security for our application. Our goal was to implement our own authentication mechanism for the web-based or user-interface portion of the application. We defined authentication security as "access rights to resources of the application". After some initial discussion, one of our business analysts suggested we look for an industry...

When my company, Amway Corp, makes a sale; somewhere, somehow a computerized transaction of that sale is created. This transaction is sent to a number of applications at Amway for processing. One such destination is our Java application. We created a capability, called the Transaction Monitor (or TM) to deliver transactions to our app. Our initial version of the TM worked well, but it was still...

We began creating our second Java application five years after we began the first app. We were hoping the second application would give us a chance to use additional Java technologies. We began by gathering all of the known functional requirements and matched them to the various Java-related technologies we knew of. The result was a high-level technical architecture of the application. This...

Java Tools

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...

Acceptance Test Driven Development (ATDD) is a very effective development practice that essentially involves writing specifications in the form of documented and automated examples. These automated examples become automated acceptance tests that validate the features being delivered. The process of writing these examples encourages teams to focus on where the business value of a feature is coming...
