Devoxx 2010, Hello JavaCommunity

Devoxx 2010 was a hit. As part of the steering committee, I've read a large number of blogs and tweets about Devoxx. I'm really happy the attendees enjoyed the conference. Speakers were great, talks were interesting and there were many interactions between developers and speakers.

RedFX and JavaFX 2.0

Tuesday, I'll give a Tools In Action talk about RedFX at Devoxx 2010. I started RedFX when the JavaFX platform was in the 1.x version. With the announcement of JavaFX 2.0, I was forced to think about how RedFX should be extended in order to make sense in the JavaFX 2.0 platform, while still providing functionality in the JavaFX 1.3.1 platform.

DaliCore, user-generated content on top of Java EE.

Most of the projects we have been doing at LodgON over the past few years have "something" to do with users and content. From a technical point, these projects typically require persistent storage, scalability, transaction support and other technologies that are offered by Java Enterprise Application Servers. Apart from these standard technologies, there are a number of common functions that we encountered in many projects, and that also require the basic technologies offered by the Java EE specification. At LodgON, we created the DaliCore code that is built on top of the Java Enterprise specification and that adds functionality commonly encountered in projects related to end-users and (their) data.

My opinion about JavaFX 2.0

It's been a few weeks since Oracle announced the plans with JavaFX. The JavaFX 2010-2011 roadmap is described at the JavaFX website. As I expected, there were many discussions and opinions in the blogosphere after the announcement. I took some time to read opinions, and to make my own impact estimations.

Java EE 6: focus on your business

I'm working with Java EE 6 for a long time. When talking with people, I often talk about the individual specs and benefits. But I realize that one of the main benefits of Java EE 6 is the overall picture. Developers can focus on the real and area-specific problems in their application, and if their project is well-written, a Java EE 6 Application Server will allow the application to scale well, to be transactional, to handle persistence,...

Oracle and JavaOne: commitment to the developer community?

JavaOne 2010 is about to start. It will be the first JavaOne under Oracle's stewardship of Java. While there will be lots of interesting sessions and BOFs during the conference, special attention will be paid to the messages Oracle is sending to the developer community.

JavaFX Open Source

I signed the petition to Open Source the JavaFX Platform. I think the benefits of Open Sourcing JavaFX can be huge, both for Oracle and the JavaFX community. The example of Glassfish, where the open community-approach leads to high quality software while still allowing a commercial model, can be followed by JavaFX.

RedFX: connecting JavaFX to the Enterprise

A couple of months ago, I started to work on RedFX (, a framework that enables an easy connection between JavaFX client-based code and Java Enterprise based backend code. I strongly believe that the connection between JavaFX and the enterprise in general is an important aspect in the chances of success for JavaFX.

Glassfish 3.0.1 on Amazon EC2: performance and scaling

Last week, our partner IvoxTools launched 3 voting tests, based on LodgON's DaliCompare software. Performance and scalability were two of the main requirements, and we realized this using a promoted build of Glassfish 3.0.1 and leveraging the Amazon Elastic Cloud Computing (EC2).

Map rendering in JavaFX

I have been writing location-based software for a long time. In this area, JavaFX has some nice benefits that allows you to write map-related software easily. As a very simple example, I wrote a map renderer that renders tiles generated by the OpenStreetMap project.
