Problem deploying Hiberhate.HAR

[kc7bfi]

I am having trouble deploying my first Hibernate HAR in JBoss. Here is my hibernate.cfg.xml:

<hibernate-configuration>
 <session-factory>
 <property name="dialect">org.hibernate.dialect.PostgreSQLDialect</property>
 <property name="show_sql">false</property>
 <property name="hibernate.current_session_context_class">org.hibernate.context.ThreadLocalSessionContext</property>
 <mapping resource="com/orci/OpenComm/db/hibernate/DatalinkProtocol.hbm.xml" />
 <mapping resource="com/orci/OpenComm/db/hibernate/EndPointGeneric.hbm.xml" />
 </session-factory>
</hibernate-configuration>

Here is my hibernate-service.xml

<server>
 <mbean code="org.jboss.hibernate.jmx.Hibernate" name="orci:name=OpenCommSessionFactory">

 <!-- Required services -->
 <depends>jboss.jca:service=HARDeployer</depends>
 <depends>jboss.jca:service=DataSourceBinding,name=OpenCommDS</depends>

 <!-- Datasource -->
 <attribute name="DatasourceName">java:/OpenCommDS</attribute>
 <attribute name="Dialect">org.hibernate.dialect.PostgreSQLDialect</attribute>
 <attribute name="SessionFactoryName">java:/hibernate/SessionFactory</attribute>

 <!-- Transaction integration -->
 <attribute name="TransactionStrategy">org.hibernate.transaction.JTATransactionFactory</attribute>
 <attribute name="TransactionManagerLookupStrategy">org.hibernate.transaction.JBossTransactionManagerLookup</attribute>
 <attribute name="FlushBeforeCompletionEnabled">true</attribute>
 <attribute name="AutoCloseSessionEnabled">true</attribute>

 <!-- Second-level caching -->
 <attribute name="SecondLevelCacheEnabled">true</attribute>
 <attribute name="CacheProviderClass">org.hibernate.cache.HashtableCacheProvider</attribute>
 <attribute name="QueryCacheEnabled">true</attribute>

 <!-- Logging -->
 <attribute name="ShowSqlEnabled">true</attribute>

 </mbean>
</server>

here is my datasource-ds.xml

<datasources>
 <local-tx-datasource>
 <jndi-name>OpenCommDS</jndi-name>
 <connection-url>jdbc:postgresql://localhost/opencomm</connection-url>
 <driver-class>org.postgresql.Driver</driver-class>
 <user-name>postgres</user-name>
 <password>postgres</password>
 </local-tx-datasource>

</datasources>

when I put it all together, I get the error:

14:57:16,906 INFO [ServiceConfigurator] Problem configuring service orci:name=OpenCommSessionFactory
org.jboss.deployment.DeploymentException: No Attribute found with name: TransactionStrategy

I confess I'm a new-be at this, but can anyone see what I'm doing wrong?
Thanks in advance,
