The World of a Penguin

SpringSource is really pushing Groovy and Grails. Hope they start pushing Jython too. Heard a nice talk just before lunch about transactions. Transactions engines are hard to write. Recomendation is to skip XA transactions. Time for some The before the next session.

One session talked about the upcoming Springframework 3.0. It is more annotations, support for validation in JPA/Hibernate beans. Most interesting is that Spring will solve the REST -problem in Java. Python and Ruby has already solved it. JAX-RS does not solve it in Java. It does not support a way to negotiating what format the result should be in (JSON, XML, HTML etc). Spring 3.0 solves this. So this will be very usefull. Spring 3 will be available early this summer. The conference has ben good so far. Two days to go. I have also attended a talk about performance tuning of Tomcat and a more detailed talk about Roo wich I mentioned from the keynote.

Some interesting notes from the keynote by Rod Johnson. SpringSource modified Eclipse environment STS for make it easier to develop Spring applications will be free from now. Their new tool Roo (may change name) to kickstart web development looks very promising. Finally something in the java world that makes simple forms development as easy as VB or Delphi.

I am attending the SpringOne conference in Amsterdam. The conference will start any minute now. The program looks very interesting. the morning here in Amsterdam was a bit cloudy but the sun is now shining. For you that did not know that; you can be full on one pancake. I just eat one with mushrooms and cheese.
