The persistence.xml file is used to define the persistence unit/s, which include
a JTA datasource that is used for database persistence. The persistence provider is
specified as org.eclipse.persistence.jpa.PersistenceProvider . The jta-
data-source is defined as java:/app/jdbc/jdbc/OracleDBConnectionDS . The
eclipselink.target-server property is specified as WebLogic_10 . The javax.
persistence.jtaDataSource property is specified as java:/app/jdbc/jdbc/
OracleDBConnectionDS , which is just the default mapping JDeveloper uses for the
JTA Data Source. The java:/app/jdbc prefix gets added to the JTA Data Source
specified when creating the persistence unit. The persistence.xml configuration
file is listed next:
