A Conversation with Java Champion Johan Vos

A new interview is now up on otn/java. In it, Johan Vos, a highly regarded Java Champion whose focus is on combining the strengths of back-end systems and embedded devices, provides his insightful take on what’s happening in the world of Java technology. His favorite technologies are currently Java EE/Glassfish at the backend and JavaFX at the front-end. He is a co-author of Pro JavaFX 2, and will be offering two sessions at JavaOne 2013.  

In the interview, Vos summarizes his sessions:

“In ‘Building Social Software on Top of Java EE 7 with DaliCore,’ I’ll show how you can integrate social software functionality into Java EE 7 applications. Many enterprise applications can benefit from some kinds of integration with e.g., Facebook, LinkedIn, Twitter, etc., without jeopardizing the user’s privacy and without giving up ownership of the data. The DaliCore framework adds the concept of User and OnlineAccount to the Java EE world, and provides the coupling with existing social networks. This saves lots of project-specific boilerplate code. This approach works both in web-applications as well as in desktop applications.

In ‘DataFX: The Best Way to Get Real-World Data into Your JavaFX Application,’ Hendrik Ebbers and I will present DataFX 2, a framework that helps JavaFX developers to populate JavaFX controls with real-world data. Now that JavaFX is beyond the stage of demos and POCs, it becomes important that the fake data used in demos be replaced with real data, often coming from back-end servers and databases. Apart from the regular cases where a JDBC source or a RESTful web service is queried, we will also show how changes in the local data can be propagated to the backend again...”

In discussing his efforts to combine Java EE and JavaFX, Vos remarks: “I am convinced that these two technologies are complementary, and while they are completely decoupled, the combination of them can lead to great end-to-end projects. As a POC, and in order to get more realistic use cases that could benefit both DaliCore and DataFX, I started to write a JavaFX application that offers community functionality. The front-end of that application is written in JavaFX, and the back-end is using DaliCore on top of Java EE 7. In this application, lots of data is sent from and to the back-end.”

In addition, Vos discusses his experiences with Java EE 7 and Java SE 8, the revolution that lambda expressions bring to Java, the client aspect of Java, how JavaFX fits into Java SE 8, and much more.
