Applications won't deploy if their persistence.xml have multiple persistence units ---------------------------------------------------------------------------------- Key: WFLY-9132 URL: https://issues.jboss.org/browse/WFLY-9132 Project: WildFly Issue Type: Bug Components: JPA / Hibernate Affects Versions: 10.1.0.Final Environment: Windows 10 64 bit Wildfly 10.1.0 Reporter: Bobby Bassman Assignee: Scott Marlow Applications won't deploy if their persistence.xml have multiple persistence units. This was not a problem with EAP. Now, Wildfly requires that each @PersistenceContext have a 'unitName' parameter. WIth EAP 6.4, if a @PersistenceContext did not have a 'unitName' parameter, then the default PU was used. By requiring that @PersistenceUnit have 'unitName', developers are forced to unnecessarily bind Java code to configuration.
