Can you describe a bit more what you expect to get, e.g. what's the metadata we need to create - URL to be passed to ORM, ... Or what's stopping you to write such deployer, which would check WEB-INF/lib jars for persistence.xml (or whatever describes persistennce unit)? What's so different from what you already wrote - your JpaDeployer? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4172303#...
