Recently, I was asked to participate in creating another Java application at my company. It was to be our team's third major Java application since 2002. We felt we had plenty of wisdom from our previous two Java applications to apply to our third one. One of our first steps was to form an application architecture sub-team. This sub-team's purpose was to provide the development team with a solid...

My company uses a large number of software applications to support all aspects of its business. These software applications are either "bought" or "built". The portions of the company that cannot be supported by purchased software are supported by custom developed, in-house, applications. A variety of technologies are used to create and build these custom applications. The Java framework has been...

A while ago, I was asked to evaluate another Java application that was being used at my company. It was a point-of-sale app, developed entirely "in-house" by one of our overseas affiliates. I wondered what their MVC model would look like. How different would their Java app be from the ones I have worked on? I started my evaluation by learning all I could about the architecture and design of this...

Very soon, it will be time for the annual Java One conference in San Francisco, California. Thousands of Java-fanatics will make the journey to my favorite city "by the bay" (and my home town). Thousands more Java-fanatics will not attend (including me) and wish they could. I hope all attendees will have a great and productive time at Java One 2013. My general advice to attendees is, "Make the...

As a developer, when you are building and/or designing a Java application; the first (or one of the first) question you might ask is... "What are the objects?" This seems to be a very simple question. But it is not. There probably is no single "right" answer to this question. Nevertheless, careful consideration given to this question will contribute to a good start to one's Java development...

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. What we...

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 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...

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)...

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;...

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...

Open Source

The 15th anniversary of OSCON showed its interest in diversity, and continuing to broaden the market for open source technology. I saw a lot of discussions on how to get people interested, and keep people involved. It was remarkably open to all sorts of ideas on how to keep open source going into the future. I started with Tim Berglund’s GitHub Power Tools, which was filled with people who had...

Education

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...

Databases

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,...
