Taken from here: http://docs.jboss.org/hibernate/stable/core/reference/en/html/persistent-classes.html#persistent-classes-equalshashcode I tend to use List since Criteria returns List, so it makes my code cleaner since I don't have to do conversion. I do something like so.. @OneToMany(cascade= {CascadeType.PERSIST, CascadeType.REMOVE}...

I'd like to set the v$session.program Oracle property in order to have information available in the session table. I'm using JPA with a jndi XA datasource created with an oracle-xa-ds.xml deployed in the deploy folder of Jboss, and therefore I haven't access to the constructor of the Connection.

I've set up a small project as a test. I'm using BlazeDS and JPA with Hibernate on my test server, and flex with with dpHibernate to access the Java entities. Each Java entity extends BaseEntity, a class that contains ID and UUID fields. The Flex entities are created by DTO2FX. My problem is that, when I run the Flex project to try and ...

there are times when I want to pass in an object to say an Auditing layer whose sole job is to persist the entities (no matter what type) , but since this is a public API, I want to ascertain that the passed in object is a hibernate entity bean and then only try the saveOrUpdate() ...
I'm trying to use Hibernate QBE (actually, Spring's HibernateTemplate.findByExample() ) to return a list of users by their username. I use a "known good" value to search on (the username "JOHN.SMITH" does exist in the database). Unfortunately, I get no results back. Below is the unit test. @Test public void testQueryByExample() { ...

Hibernate Gurus, I have a pesky issue and I don't really know how to solve my problem. I have a solution, however, I feel I may be reinventing the wheel. I have two entities, The first is a User Object, The second is an Alias Object. The relationship between the two is that A USER can have multiple ALIAS(es) and an ALIAS can be tied to...
I'm trying to use Hibernate for the first time, and early on in the getting started guide, it makes reference to Maven. If I'm not mistaken, Maven appears to be a build tool. However, I've been using Eclipse to build my project up to this point. Is there a way for me to use Hibernate without needing Maven? Can I just do what I need t...

I am trying to work out how to do the mappings for two different projects that share some entities. Since they share only a limited subset of mappings, my first idea was to separate these mappings out into a separate jar. I'm using hibernate annotations to do the mappings (so they're in the class files, not separate XML). Both project A...
