[jboss-user] [JBoss Seam] - Seam 2 beta and JPA

[jasondlee]

I'm trying to get a Seam 2 app working under OC4J 10.1.3.  It's going mostly OK, but I'm getting some exceptions regarding my EntityManagerFactory that I can't seem to figure out.  Here are my persistence.xml and components.xml files:


  | <persistence xmlns="http://java.sun.com/xml/ns/persistence"
  | 	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  | 	xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
  | 	version="1.0">
  | 	<persistence-unit name="em" transaction-type="RESOURCE_LOCAL">
  | 		<provider>org.hibernate.ejb.HibernatePersistence</provider>
  | 		<jta-data-source>jdbc/Dev</jta-data-source>  
  | 		<!-- Snip -->
  | 		<exclude-unlisted-classes>true</exclude-unlisted-classes>
  | 		<properties>
  | 			<property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
  | 		</properties>
  | 	</persistence-unit>
  | </persistence>
  | 

and

  |                   conversation-id-parameter="cid"/>
  |     
  | 
  |     <persistence:entity-manager-factory      name="entityManagerFactory">
  |     </persistence:entity-manager-factory>
  |     <persistence:managed-persistence-context name="entityManager"
  |                                              auto-create="true" 
  |                                              entity-manager-factory="#{entityManagerFactory}" />
  | </components>

The exception I get varies, but currently I'm getting "org.hibernate.HibernateException: Hibernate Dialect must be explicitly set" but it looks to me like it is being set.  What am I missing?

Thanks!
