    Configuring the persistence-unit provider

    tom harel Newbie

      Hi,

       

      What would be the correct way to Configuring the persistence-unit provider and other hibernate properties ?

       

      I have started working with the test cases you provided and am now working on incorporating Cassandra as the database.

      I am trying to use OSG as the jbos component that will connect the Cassandra database with the hibernate FW.

      OSG examples explain that the fallowing change is needed in the persistence.xml , however persistence.xml is not used in your examples and it not clear to me where the needed changes should be made.

       

      <!-- when using a relational database -->

      <persistence ...>

          <persistence-unit name="users" transaction-type="RESOURCE_LOCAL">

              <properties>

                  <property name="javax.persistence.jdbc.driver" value="org.h2.Driver"/>

                  <property name="javax.persistence.jdbc.user" value="sa"/>

                  <property name="javax.persistence.jdbc.password" value=""/>

                  <property name="javax.persistence.jdbc.url" value="jdbc:h2:tcp://localhost/./intro-ogm"/>

                  <property name="hibernate.dialect" value="org.hibernate.dialect.H2Dialect"/>

                  <property name="hibernate.hbm2ddl.auto" value="update"/>

                  <property name="hibernate.max_fetch_depth" value="3"/>

              </properties>

          </persistence-unit>

      </persistence>

       

      <!-- when using Hibernate OGM -->

      <persistence ...>

          <persistence-unit name="users" transaction-type="RESOURCE_LOCAL">

              <provider>org.hibernate.ogm.jpa.HibernateOgmPersistence</provider>

              <properties>

                  <property name="hibernate.ogm.infinispan.configuration_resourcename"

                            value="META-INF/ispn-config.xml"/>

              </properties>

          </persistence-unit>

      </persistence>
