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! This year, Sunday is already overcrowded with many more events and sessions than one can possibly attend, as the JavaOne 2013 Content Catalog Sunday entries demonstrate. Sunday's activity can be divided into...

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...

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 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...
