Thanks Kevin - I am the stupid new boy. I changed the reference and the building is OK now.
I've now got a new problem with my my JUnit test: javax.persistence.PersistenceException: Explicit persistence provider error(s) occurred for "address-pu" after trying the following discovered implementations: org.apache.openjpa.persistence.PersistenceProviderImpl, org.eclipse.persistence.jpa.PersistenceProvider from provider: org.apache.openjpa.persistence.PersistenceProviderImpl at javax.persistence.Persistence.createPersistenceException(Persistence.java:242) at javax.persistence.Persistence.createEntityManagerFactory(Persistence.java:184) at org.firstutility.addressjpa.utility.EntityManagerUtility.getEntityManagerFactory(EntityManagerUtility.java:29) at org.firstutility.addressjpa.utility.EntityManagerUtility.getEntityManager(EntityManagerUtility.java:41) at org.firstutility.test.addressjpa.utility.EntityManagerUtilityTest.testGetEntityManager(EntityManagerUtilityTest.java:35) Caused by: <openjpa-2.0.0-beta-r422266:903062M nonfatal general error> org.apache.openjpa.util.GeneralException: org.xml.sax.SAXException: file:/home/schong/svn/ProofOfConcept/addressJPA/target/classes/META-INF/persistence.xml [Location: Line: 8, C: 134]: org.xml.sax.SAXParseException: cvc-complex-type.3.1: Value '1.0' of attribute 'version' of element 'persistence' is not valid with respect to the corresponding attribute use. Attribute 'version' has a fixed value of '2.0'. So, I started a completely new project and used the NetBeans Persistent Unit wizard, choosing EclipseLink(JPA 2 0) as the persistence library. It gave me this in the persistence.xml: <persistence version="2.0" xmlns="http://java.sun.com/xml/ns/persistence" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/persistence http://java.sun.com/xml/ns/persistence/persistence_2_0.xsd"> I don't have any dependencies on Open JPA now. - Everything builds fine and my JUnit tests run fine. I am guessing that there is some kind of wierd interacction between NetBeans and the Open JPA I was using.
