Java EE 6 And Rethinking - JUG HH Afterglow : Adam Bien's Weblog

Java EE 6 And Rethinking - JUG HH Afterglow : Adam Bien's Weblog Adam Bien's Weblog « How Big Is Actually... | Main | My Top 3 "No XML"... » Java EE 6 And Rethinking - JUG HH Afterglow I really enjoyed the session at Lehmann's (cool book store with impressive amount of not only Java books).  It was organized by JUG in Hamburg . We had interesting, late night, discussions - and finally some consensus: DAO is not completely dead - only in the majority of all cases :-). EJB 3.1 are lighter than expected Wicket is cool and JSF just works - especially with EJB 3.1. OSGI inside the applicationserver could solve some interesting problems in HA and highly dynamic environments. Layering is not always good. WAR deployment of no-interface beans is interesting for small web apps with databinding... Async methods are interesting - especially in case they can be monitored and managed by the appserver. Singletons are interesting for pre-initialization etc. ...and other stuff - it was finally to late. This time I used GF v3 prelude b24 with Netbeans 6.5 development build (200809130201) to show some new stuff. It worked surprisingly well...Thanks to the organizers!

Newsletter: airhacks.news A book about rethinking Java EE Patterns Comments: Regarding point 7: You mentioned that Async methods can be taken into account as an alternative to JMS in some circumstances. I fully agree with that and want to give just a little remark: I can imagine that it would be more "light weight", i.e. will use less resources as JMS and so can be faster and/or more compact. That is because of the implementation on the basis of the Future mechanism and such stuff is running only in memory whereas JMS is using Databases (at least I do not know of another way). Okay, the Async feature will certainly not support recoverable transactions or persistent states which will be recovered after a server crash-and-restart, hence will not guarantee the processing of the method, but many asynchronous tasks don't need such "recoverablility".
