Its about 6.30PM here in Prague and the day 1 of The Server Side Java Symposium (TSSJS) is wrapping up for the day with an award ceremony (sponsored by GigaSpaces). I am too tired and sleepy to carry on after yesterday's long flight and lack of sleep but thought of posting a few interesting things that I noticed here at the symposium today.
Firstly the venue and the setup is pretty cool and there are over 300 people from many parts of Europe. The day started with a brilliant keynote by Stephan Janssen. His topic being: Supporting the RIA Space. (A Java conference kickstarts with a talk on RIA -- interesting! isn't it?). If you were at JavaOne this year and attended Stephan's talk then you probably heard a lot of this. I had to step out of his talk a little early to get setup for my own talk, which followed Stephan's. I spoke about JPA/Hibernate and RIA integration. Was happy to have a house full of attendees at my talk but was surprised when I saw only a few hands go up on my question: "How many of you are familiar with RIA?". In fact a few were getting familiar with the subject only from the keynote that had preceeded my talk. Very interesting, again!
TSSJS speaker lineup is quite impressive. There were talks by many well known people, including Nati Shalom (GigaSpaces), Alexandru Popescu (InfoQ), Michael Keith (EJB 3.0), Guillaume LaForge (Groovy/Grails), Holly Cummins (IBM) and Geert Bevin (Terracotta, UMYN & RIFE) on day 1 itself. There were many other good speakers today: its just that I presume the ones I listed are better known than others. There are many more good speakers in the next couple of days to come. Obviously I could not attend all the sessions today so it would be unfair for me to comment much about the ones I never even peeked into.
Both the Groovy talks (Alexdru's and Guillaume's) were cool and well attended. Java Performance (Holly's) and JVM Clustering (Geert's) were very popular as expected.
These days when you go to a Java conference its a lot about dynamic languages (and their existence on the JVM) and the first day here reinforced the same feeling. However, one interesting change was a company called ZeroTurnAround , which promised dynamic redeployment of Java applications (far better than the JVM HotSwap). Their tool is called JavaRebel (I spoke with Jevgeni -- who carries a fascinating title of Lead Rebel in the company) and he was kind enough to walk me through a lot of examples where Java code could be redployed effortlessly. There message could be interpreted as: "Java can be dynamic in some ways too, without being dynamically typed or interpreted!" If you are a Scala fan, you will be happy to know that JavaRebel comes built-in with Lift, the emerging Sacla framework. Talking about frameworks, there are too many in the world of Java to catch up these days and that is the topic of my next presentation at TSSJS this Friday. I am not going to miss the opportunity to express my frustration dealing with over supply then! Wish these framework makers found a way to create alternative energy sources; with their commitment there with be no oil crises today :)
