I'd like to create one Bundle that is able to use Java Persistence. To achieve this, I've created a plugin project within Eclipse. In my project, I've created a persistence.xml file into META-INF. I've aslo added in my MANIFEST.mf (into the depencies) those 3 packages : javax.persistence.jar org.eclipse.persistence.jar org.eclipse.persistence.jar Then, in my Activator I use this lines to create an EntityManager : factory = Persistence.createEntityManagerFactory(PERSISTENCE_UNIT_NAME); EntityManager em = factory.createEntityManager(); To execute my bundle, I've made a product configuration.

Is there a possiblity in JPA 2.0 to set a collection for in-clause in jpql-query? (I'm using EclipseLink) The next example fails: TypedQuery<Person> q = em.createQuery("select p from Person p where p.name in (?1)", Person.class); List<String> names = Arrays.asList(new String[] { "Bill Gates", "Steve Jobs" }); // THIS FAILS q.setParameter(1, names); List<Person> persons = q.getResultList(); for (Person p: persons) { System.out.println(p.getName()); } Is there another way to do it? Here is what the JPA 2.0 specification says about IN expressions: 4.6.9 In Expressions The syntax for the use of

I'm trying to persists JodaTime DateTime fields with JPA to PostgreSQL but run into troubles with null pointers to database NULL values. I'm working with the NetBeans 7 beta 2 IDE. The persistence implementation is EclipseLink 2.2.0 and I'm using an EclipseLink Converter to get the mapping to work. Here is the declaration of my field: @Converter( name="dateTimeConverter", converterClass=ejb.util.DateTimeConverter.class ) @Column(columnDefinition="TIMESTAMP WITH TIME ZONE") @Convert("dateTimeConverter") private DateTime testdate; The converter class: public class DateTimeConverter implements

I'd like to add support for the Java 8 Date/Time API (JSR-310) in my JPA-enabled application. It's clear that JPA 2.1 does not support the Java 8 Date/Time API . As a workaround, the most common advise is to use an AttributeConverter . In my existing application, I changed my entities to use LocalDate / LocalDateTime types for the column mapping fields and added legacy setter/getters for java.util.Date to them. I created corresponding AttributeConverter classes. My application does now fail when using Query.setParameter() with java.util.Date instances (it worked before the transition to the

I am using Netbeans 7.1.1 and a Glassfish 3.1.2 server. As JPA provider I decided to use eclipse-link 2.3.0 which is shipped with Netbeans. Since I want to use lazy fetching and my project consists of roughly 45 JPA Entity classes which do have lots of relations among them, I decided to use static weaving . Moreover, the @Entity classes are in a separate Class Lib Project, whereas the persistence.xml resides in the EJB project. I already followed the instructions here: http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Advanced_JPA_Development/Performance/Weaving/Static_Weaving I put the ant

I have an entity mapped as following: @Entity @Table(name = "Groups") @IdClass(value = GroupId.class) public class Group implements Serializable { @Id @Column(name = "round_id") private Integer roundId; @Id @Column(name = "ordinal_nbr") private Integer ordinalNbr = 0; ... } It has a composite key (round_id, ordinal_nbr) to indicate the order of groups in a round. Now imagine a join table containing entities that link the ordered groups via a self reference (from Group to Group): CREATE TABLE GroupLinks ( parent_round_id INTEGER NOT NULL, parent_ordinal_nbr SMALLINT NOT NULL, child_round_id
