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/ directory.
<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/my-mappings.xml</mapping-file> ... <jar-file>my-additional-jar.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.
See Developing JPA Projects in the EclipseLinkUser's Guide for details.
