Hi Adam, thank you. If I remove the <mapping-file> I still get the same error. I change the header to your header but still no difference. I paste the new version of my files below.
Both orm.xml and persistence.xml are in the same directory META-INF. Any further advice? -------------- <?xml version="1.0" encoding="UTF-8"?> <entity-mappings xmlns="http://java.sun.com/xml/ns/persistence/orm"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; xsi:schemaLocation="http://java.sun.com/xml/ns/persistence/orm http://java.sun.com/xml/ns/persistence/orm_1_0.xsd"; version="1.0"> <entity class="datamodel.Person"> <table name="MYAPPLICATION.PEOPLETABLE"/> <attributes> <id name="id" /> <basic name="firstName" /> <basic name="lastName" /> <transient name="nonsenseField" /> </attributes> </entity> </entity-mappings> <?xml version="1.0" encoding="UTF-8"?> --------------- <persistence xmlns="http://java.sun.com/xml/ns/persistence"; xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"; version="1.0"> <persistence-unit name="people" transaction-type="RESOURCE_LOCAL"> <provider> org.apache.openjpa.persistence.PersistenceProviderImpl </provider> <mapping-file>META-INF/orm.xml</mapping-file> <!-- We must enumerate each entity in the persistence unit --> <class>datamodel.Person</class> <properties> <property name="openjpa.ConnectionURL" value="jdbc:derby:C:/DerbyDatabases/hellojpa-database9;create=true" /> <property name="openjpa.ConnectionDriverName" value="org.apache.derby.jdbc.EmbeddedDriver" /> <property name="openjpa.ConnectionUserName" value="" /> <property name="openjpa.ConnectionPassword" value="" /> <!-- Automatically create tables in the database for entities.
