Ok, so back to my original post. I guess this doesn't have anything to do with EJBs. So here's what I i'd like to know now... I have two Hibernate3 cfg.xml files (two dbs) and lots of hbm.xml mapping files. I'd like to use these with Seam in the 'best' way possible. Can anyone advise what configuration I should use? i.e. do I need the microcontainer and a jboss-beans.xml? If so, do I also need the -ds.xml datasource file? And where do these go in Jboss? Both in the deploy dir? OK enough questions! I fiddled with the seam-gen-erated project to get it working with Hibernate, and having read the reference guide (Chapter 21), I decided not to use the microcontainer (since I'll be using Jboss 4 anyway). Is this the right decision to make? Lindsay View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4036345#...
