Java EE 5 can be really efficient - you just have to get rid of 50 superfluos layers, and abstractions :-). During the "Entwicklertage" workshop in Frankfurt, I will introduce some lean patterns and best practices and we will build together with the students a fully functional Java EE 5 application - in very green filed fashion. We will even install the whole infrastructure (JDK, IDE, server) during the workshop - so it will be nearly "real world". ...best critics, questions and heretical statements about Java EE 5 will be rewarded with a t-shirt :-).
Beyond that I will disect the Run And Bike application to explain some presentation patterns as well.
