My team developers are Not familiar with Hibernate.(I know that much Hibernate-knowledge is not needed to use jBPM.but if anything happen in hibernate,it would be panic...) 2. I don't know well about passing the jdbc connection from iBatis to the hibernate Session on the same transaction... That's it. I apologize that you guys expected much more smart things. I appreciate lots of responces, anyway! btw, standard is not big deal around me recently. JEE6 doesn't show up yet, I can't wait. ;-) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4204342#...
