Hello, I have one .jar with a lot of entities and a persistence.xml file with two "persistence-unit". In production environment, there will be a lot of servers on different sites with the .jar. In the future, how can I "extract" and isolate the persistence.xml file from the .jar to update only the .jar file and not the persistence.xml file to maintain the config of the persistence-units ? Thanks in advance. Olivier View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3989857#...
