calm down please ;) 1) If you want specific features in the generated code then please contribute it - its just a matter of adding/fixing the templates. 2) seam-gen as it is in the ant scripts is just done via reverse engineering but hibenate tools supports using existing entities just fine and there are even a jira for it to be applied - someone just need to pick that up and get it applied properly. It's described at http://jira.jboss.com/jira/browse/JBSEAM-843 and even with a patch you can easily try out if you want. 3) Just to prove it works - then In JBoss Tools you have two options when you choose seam generate entities you have the option of selecting Reverse Engineer from database OR Use exiting entities.
