Inaugural JavaLand in Germany It took trains, planes, and automobiles to get there. I had heard Germany ran some great conferences, but JavaLand was promised to be outstanding. Kevin already did an interview with one of the organizers, Markus Eisele, about why JavaLand is different. (https://weblogs.java.net/blog/editor/archive/2014/03/01/java-conferences...) But, I got to see first-hand if they...

In late January I considered what I'd do if I had several free months to wander Europe. A look at the Lanyard Java Conferences calendar gave me a great idea: I could wander through Europe from Java conference to Java conference, while also enjoying everything in between! My imaginary trip started in Stockholm, Sweden, with Jfokus 2014. I'm now traveling 1400 km southwest, to Brühl, Germany, for...

Introduction to Class Diagram In any project's planning phase, the programmer should describe the behaviour of the different objects that are required to satisfy business use cases. However objects can't emerge from nothing, so you need a template that describe the type of objects that the system will have. As a result, you will need to show a diagram with all the classes involved and their...

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...

Looking Forward to JavaOne Sunday: JUG Forums, NetBeans Day, GlassFish, Technical Keynotes, Duke's Choice Awards It used to be that Sunday was a fairly relaxing day for most. Not anymore!

My company uses a large number of software applications to support all aspects of its business. These software applications are either "bought" or "built".

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...
