I'm already looking forward for the JUG cologne event (02.04.2007). After introducing some general architectural ideas, I will present some (controversial) Java EE 5 patterns (with MB's of sourcecode) and idioms and try to answer the quesion whether J2EE patterns where workarounds or not. I hope this session will be interactive, otherwise it could become too esoteric.
Afterwards we could discuss also some voodoo consulting and java guru stuff :-).
