Java User Groups

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...

Embedded

I've finally found time to start browsing the JavaOne 2013 Content Catalog, andand various summaries of interesting JavaOne sessions organized by topic (you can see several of these on the Java.net home page right now). Thanks to Terrence Barr's "JavaOne 2013: Deep into Embedded" post, I came across Controlling NAO Robot with Java [CON11839]. The session is presented by Dimitri Merejkowsky,...

One of the most interesting things about JavaOne is the announcements. Some years, there isn't a single big announcement, while other years something of enduring significance is announced or released during JavaOne. While we won't know what surprise announcements or releases this year's conference will include, a look at the conference agenda, the keynotes, the tracks, and the sessions, can give...

javax.servlet.http.HttpSession provides a way to identify an user across multiple HTTP requests and to store user specified information. In other words, it provides a support of stateful communications with the stateless HTTP protocol. For security and memory management, sessions need to be invalidated at a certain time. There are two related methods in HttpSession. HttpSession.invalidate() By...

Java Web Services and XML

Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. JAX-RS provides a standardized API for building RESTful web services in Java. This example will show how to...

I'm expanding on an earlier post where I explained how to deploy JAX-RS Web Services to the Oracle Cloud. In that entry the web service simply returned a hard-coded "Hello World". In reality, you most likely want your web service to expose something more meaningful. In this post I'm going to expand the HelloJerseyApp to display the results from a table, which I'll expose using a JPA...

Java Patterns

I had the pleasure of speaking at JavaZone in Oslo this year. Here is a collection of links of the talks I attended. Hadi Hariri from JetBrains plugs his Kotlin based JavaScript web app framework. Ample context is given to place this offer in the context of the new crop of thin-server architecture solutions. Video Mario Fusco from RedHat gives a masterful...

Java Tools

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...

Java Desktop

Visual Library is a library in NetBeans, which you can use in standalone Java apps, for doing beautiful, complex, animated layouts. JUNG is a library for exploring graphs of connected data. What if we put those two things together? That's what I did. The result is on GitHub. Video demo and more info over on my timboudreau.com blog.
