openjpa

I'm using Hibernate 3.4 on Websphere 7, with Spring 2.5.6 On startup, my application seems to have problems with Hibernate vs. OpenJPA: 10/02/12 10:41:50:448 GMT] 00000010 LocalEntityMa I org.springframework.orm.jpa.LocalEntityManagerFactoryBean createNativeEntityManagerFactory Building JPA EntityManagerFactory for persistence unit 'mypu' [10/02/12 10:41:50:495 GMT] 00000010 SystemErr R WARNING: Found unrecognized persistence provider "org.hibernate.ejb.HibernatePersistence" in place of OpenJPA provider. This provider's properties will not be used. ... and then a lovely stack trace caused by:

Im trying to change the default JPA implementation of Hibernate to OpenJPA on Spring boot. Ive searched on google but there is not much on how to configure openJPA to Spring boot. Any advice would be helpful. Thanks @Configuration public class OpenJPAConfig extends JpaBaseConfiguration { protected OpenJPAConfig(DataSource dataSource, JpaProperties properties, ObjectProvider<JtaTransactionManager> jtaTransactionManager, ObjectProvider<TransactionManagerCustomizers> transactionManagerCustomizers) { super(dataSource, properties, jtaTransactionManager, transactionManagerCustomizers); } @Override

This is a simple program to write to and read from a mysql database. When I enter the test data, all of it is visible in the mySQL client. Yet, when I use OpenJPA to retrieve the same data, all the ids appear "0", but the names are correct. What might be the cause for IDs to get lost during the transaction? POJO Class import java.io.Serializable; import javax.persistence.*; @Entity (name="People") public class People implements Serializable{ /** * */ private static final long serialVersionUID = 801578124126646759L; @Id private int id; @Column(length=32) private String name; public People(int

Does OpenJPA have any support for batch insert similar to Hibernate ? I haven't found it in the docs, but I'm hoping I missed it. I know JPA doesn't support it in general . Short answer, yes. Longer answer, take the link to Hibernate documentation and replace the Session with a JPA EntityManager. EntityManager em = emf.createEntityManager(); Transaction tx = em.getTransaction(); tx.begin(); for ( int i=0; i<100000; i++ ) { Customer customer = new Customer(.....); em.persist(customer); if ( i % 20 == 0 ) { //20, same as the JDBC batch size //flush a batch of inserts and release memory: em.flush
