To use JPA you will need to have the following configurations available:
- Persistence.xml - which defines your persistence units and should be in the meta-inf/
<persistence-unit name="default" transaction-type="RESOURCE_LOCAL">
<provider>org.eclipse.persistence.jpa.PersistenceProvider</provider>
<!-- By default your mappings can be defined in orm.xml file, -->
<!-- which is discovered automatically. -->
<mapping-file>META-INF/advanced-entity-mappings.xml</mapping-file>
...
<jar-file>jpa-xml-only-model-tests.jar</jar-file>
...
<exclude-unlisted-classes>false</exclude-unlisted-classes>
<properties>
...
</properties>
</persistence-unit>
- Entities, Embeddable and MappedSuperclasses
- These classes should be decorated with the necessary annotations, and/or
- Be defined in the orm.xml (or some other mapping file) using the XML descriptors.
- Properties - use these properties to further configure your JPA application.
- javax.persistence.transactionType - Standard JPA PersistenceUnitTransactionType property, JTA or RESOURCE_LOCAL.
- javax.persistence.jtaDataSource - Standard JPA JTA DataSource name.
- javax.persistence.nonJtaDataSource - Standard JPA non-JTA DataSource name.
