    [ https://issues.jboss.org/browse/AS7-2275?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12641516#comment-12641516 ] 

Scott Marlow commented on AS7-2275:
-----------------------------------

>From this forum post (http://community.jboss.org/thread/152958), it sounds like JBoss 4 worked like this jira proposes (via check in org.jboss.ejb3.enc.DeploymentPersistenceUnitResolver).  Then JBoss 5/6 changed that and we are talking about changing back.  I agree that JBoss 4 was better but want to understand more.

I certainly don't mind requiring applications to be more concise about which persistence.xml definition that they wish to use.  I'm also unsure if AS7 will use the same persistence.xml that AS5/6 does.
