Max, Can you offer any suggestions for using the plugin when you're using Tomcat JDNI? Is there a simple way to keep two hibernate.cfg.xml files in sync? OR Do you comment out/delete the <property name="hibernate.connection.datasource"> line when you want to use the hibernate plug-in features? Any suggestions? Thanks.
