I understand the deferred constraint issue is going to be fixed in JBoss 4.0 if not sooner. IMO this is a major stumbling block in terms of porting weblogic applications. We had to defer constraints and were able to do that because we owned the schema. There are plenty of situations where a change of that magnitude would never fly. I also think Middlegen samples could be a lot better such as a CMP application for each supported platform versus the current swiss-army example. Perhaps somebody will contribute a simple ANT script for that since it spoon feeding users is not a fate Alsak deserves after all his hard work on giving us this tool.
