Jazoon Day 3
Again I didn’t have time to attend Jazoon all day. This is the downside if the conference takes place in the city where you live and work. Customers usually have a higher priority than attending a conference.
The first talk I attended was about “Effective Java Heap Memory Analysis on Enterprise-Scale” by Lerenc Vedran. The guys at SAP developed a tool to analyse a Java heap dump (Usually a result of a OutOfMemoryError) from the perspective of the garbage collector. I was quite impressed what kind of information you can gain by using this tool and how easy it is to find the memory hogs in your application. Finding memory leaks is usually far easier than identifying the greedy classes which are not leaking but nevertheless take up huge amounts of memory. Any serious Java application on an enterprise scale needs this kind of analysis since memory tends to be a constrained resource. You can find more information about the SAP Memory Analyzer and the free download here: https://www.sdn.sap.com/irj/sdn/wiki?path=/display/Java/Java+Memory+Analysis&
Next I listened to “JavaFX Script – Declarative GUI Programming Language for the Java Platform” by Anatoli Fomenko and Gregory Murray from Sun Microsystems. Having been at JavaOne the contents of this talk was nothing new to me and the speakers did not really dive into the technical details of Java FX. The biggest surprise, however, was that one of the demos they showed was Canoo’s Music Pinboard.
My last talk was “Spring 2.1: Dependency Injection and AOP in a Java EE 5 World” by Jürgen Höller. Having suffered a lot from the complexities of Java EE it always amazes me how Spring sustains to simplify development without sacrificing the ability to tackle complex problems. Jürgen presented the features of the upcoming Spring 2.1 release which focuses on using annotations for even more seamless integration into Java EE. Jürgen is a good speaker and I enjoyed this update on the Spring future straight from the horse’s mouth.

Hey Bruno… not sure why you were “surprised” by the Sun presentation. Music Pinboard is a totally cool looking application

European software developers tend to be neglected by American companies. Hence, I was surprised that Sun Microsystems discovered Canoo\’s Music Pinboard and even uses it to show off Java FX.
