Seam example with postgres

[eerriicc]

Hello everyone!
I´m running the booking example perfectly
but I would like to change to postgres DB!
How can I do that? please somebody help me!

I´ve done that:
obs: I remove the closed and opened tags...
on booking/resources/META-INF/persistence.xml

<persistence-unit name="bookingDatabase" transaction-type="JTA">
     <provider>org.hibernate.ejb.HibernatePersistence</provider>
     <jta-data-source>java:/PostgresDS</jta-data-source>
     <properties>
        <property name="hibernate.dialect" value="org.hibernate.dialect.PostgreSQLDialect"/>
        <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
        <property name="hibernate.jdbc.batch_size" value="20"/>
        <property name="hibernate.transaction.manager_lookup_class" value="org.hibernate.transaction.JBossTransactionManagerLookup"/>
     </properties>
  </persistence-unit>

jboss-seam-booking-ds.xml:

<datasources>  
     <local-tx-datasource>  
          <jndi-name>PostgresDS</jndi-name>
          <connection-url>jdbc:postgresql://127.0.0.1:5432/mydbtest</connection-url> 
          <driver-class>org.postgresql.Driver</driver-class> 
          <user-name>postgres</user-name> 
          <password>passwd</password> 
     </local-tx-datasource> 
</datasources>
