Callback methods are user defined methods that are attached to entity lifecycle events and are invoked automatically by JPA when these events occur. Internal Callback Methods Internal callback ... methods for any subset or combination of lifecycle events but no more than one callback method

store separate entity for given event . Right now I'm using BaseEntity which contains @ElementCollection private Set activities; This way I can add events to given object without using EM to persist new ... final boolean onPreUpdate(PreUpdateEvent event ) {         try

Hello, is there a way that lifecycle events like prepersist or preupdate are also fired for embeddable classes, not just for entities? My case looks as follows: @Entity public class Foo { @Id ... ; objectArts objectArts JPA lifecycle events are not applicable for embeddable classes. You can set an event

This is not supported. You may be able to implement your own cross process event listeners based on the JPA event listeners if every process will listen to its own events and will report to other processes. support Support

This chapter explains how to manage ObjectDB databases using the Java Persistence API (JPA). The first two pages introduce basic JPA interfaces and concepts: The next section explains how to use JPA for database CRUD operations: More advanced topics (e.g. locking and events ) are discussed in the last section:

JPA defines dozens of annotations that can be divided into the following groups: Annotations for JPA aware classes: Annotations for fields in JPA persistable classes: Annotations for additional JPA configuration: Annotations for JPA lifecycle event callbacks: Java EE container annotations: Many

JPA defines three types of persistable classes which are set by the following annotations: Chapter 2 of the ObjectDB manual explains these annotations in detail. Entity and mapped super classes can be further configured by annotations that specify cache preferences and lifecycle event listener

The following annotations can mark methods as JPA callback methods: The Lifecycle Events section of the ObjectDB Manual explains how to use all these annotations on callback methods and with listener classes.

Hello, I have 3 entity classes: Event - String title Calendar - List @OneToMany SharedCalendar extends Calendar - Calendar original Now I want to retrieve all events from a specific calendar by its id like: SELECT event FROM Calendar c1, SharedCalendar c2 INNER JOIN c1. events AS event INNER JOIN

{ @Id private String id; @OneToMany(mappedBy="town") private Set events ; public Set getEvents() { Set events = new HashSet (); if(this. events != null) { events .addAll(this. events ); } return events ; } public void setEvents(Set events ) { this. events = events ; } } Storing the objects works fine

The following interfaces can be implemented by persistence capable classes in order to response to JDO lifecycle events :

The following types can be used to implement external listener classes for JDO lifecycle events : Listener objects can be bound to one or more persistence capable classes by invoking the addInstanceLifecycleListner method either at the PersistenceManagerFactory level or the PersistenceManager level.
