Another good day at devoxx, more surprises: keynotes don’t have to be boring marketing talks. The day started with 2 good keynotes by sun. The first by Joshua Bloch, containing lots of code and good tips from his book: Effective Java. The next keynote presented the plans to modularize Java starting with Java 7. You can find more info here Java SE: Project Jigsaw: Modularizing JDK 7, and on Mark Reinhold’s blog

Paul Fremantle did a presentation on Event Driven Architecture and Complex Event Processing, showing examples using Apache Synapse and Esper. CEP seems very usefull in situations where you have to find informations in a large number of events. Currently Esper can be used in Synapse. Not sure how easy it integrates with other ESBs. Would be nice to have it available as an OSGi bundle, which can be used in Spring DM, ServiceMix 4, and Glassfish 3.

Next up: a talk about using Geospatial Software to create a website for kitesurfers. I do a lot of kitesurfing and windsurfing myself, so i had to see this presentation. After a short introduction, the presenter demoed how you can build geospatial websites using open source software. It was interesting to see, but not really about programming. You can achieve most of what you want using existing software, it’s mostly about configuring the software and loading the data.

Paul Sandoz did a talk on JAX-RS and the Jersey implementation. I haven’t used JAXRS yet, as i’ve been doing most of my REST stuff using Grails, which is dead easy. But Jax-RS seems like a pretty good way to do it in java. Also, i learned that they have support for JSON in JAXB, which i wasn’t aware off.
