[jbossseam-issues] [JBoss JIRA] Closed: (JBSEAM-1160) EMF implicit lookup/resolve precedence

EMF implicit lookup/resolve precedence -------------------------------------- Key: JBSEAM-1160 URL: http://jira.jboss.com/jira/browse/JBSEAM-1160 Project: JBoss Seam Issue Type: Feature Request Components: Core Reporter: Christian Bauer Assigned To: Gavin King Fix For: 1.3.0.ALPHA Currently impossible to use WAR deployment and Unit testing. Only way to configure it is as follows: <core:managed-persistence-context name="entityManager" auto-create="true" entity-manager-factory="#{wikiEntityManagerFactory}" persistence-unit-jndi-name="java:/EntityManagerFactories/wiki"> </core:managed-persistence-context> <core:entity-manager-factory installed="@seamPersistenceUnit@" name="wikiEntityManagerFactory" persistence-unit-name="wiki"/> <core:ejb installed="@embeddedEjb@"/> So either the EMF is started by Seam during WAR deployment (seamPersistenceUnit) and available as a component instance in application scope, or the EMF is deployed by the E-EJB3 container and bound to JNDI with the magic JBoss configuration property in persistence.xml. The managed-persistence-context now needs to access the EMF polymorphically, no matter where it is bound. If you try the above code, you will see that the entity-manager-factory attribute always has precedence, and if it resolves to null, you get an NPE. Instead, the JNDI lookup should be attempted.
