RE: Trouble building the sample code

I do not use the SeqBlock or Sequence beans...I thought they were Oracle specific, but I might be thinking of one of Middlegen's generic UID generators. 

As for hibernate versus cmp20, it is only a small deal in so far as changing (or adding in another) Ant tasks/Maven goals (which isn't that hard).  However, by switching persistance you may break your business code if it has dependencies already on your persistance layer.  I will mention using hibernate will eliminate all the problems you have mentioned so far in the tutorial for Middlegen.

CMR issue - Known problem with Jboss deployments. I personally don't use CMR anymore because of this (and sometimes better for more specific business-rules-relations).
