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>
| 
| <exclude-unlisted-classes>true</exclude-unlisted-classes>
| <properties>
| <property name="hibernate.dialect" value="org.hibernate.dialect
.PostgreSQLDialect"/>
| </properties>
| </persistence-unit>
| </persistence>
|

and

| </persistence:entity-manager-factory>
| <persistence:managed-persistence-context name="entityManager"

| </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!
