persistence.xml Hibernate JPA

Abaixo o persistence.xml para usar Hibernate com JPA no JBoss com Datasource.

<persistence-unit name="jpaPU">
<provider>org.hibernate.ejb.HibernatePersistence</provider>
<jta-data-source>java:/DerbyDS</jta-data-source>
<class>com.jboss.entities.Country</class>
<properties>
 <property name="hibernate.dialect" value="org.hibernate.dialect.HSQLDialect"/>
</properties>
</persistence-unit>

JBoss já disponibiliza uma série de propriedades pré-configuradas para o uso de JPA com Hibernate no arquivo /server/default/deploy/ejb3.deployer/META-INF/persistence.properties. Você pode usa-lo para ter uma idéia das propriedades que poderão ser sobrescritas no seu persistence.xml.

Segue a lista abaixo:

#hibernate.connection.release_mode=after_statement
#hibernate.transaction.flush_before_completion=false
#hibernate.transaction.auto_close_session=false

# Clustered cache with TreeCache
#hibernate.cache.provider_class=org.jboss.ejb3.entity.TreeCacheProviderHook
#hibernate.treecache.mbean.object_name=jboss.cache:service=EJB3EntityTreeCache

hibernate.bytecode.use_reflection_optimizer=false
# I don't think this is honored, but EJB3Deployer uses it
