7. Enumeration mapping JPA java.net
In our database we have an enumeration of strings. All these strings are actually numbers, for example ['-2', '-1' ,'1' ,'2']. At first I wanted to create an enumerator in Java for this but I couldn't find out how to do it, since enumerated values cannot start with a number. Then I thought that I could use an int in my ...

10. Implementing Joined Inheritance in JPA java.net
I'm not sure of the problem you are trying to solve, but there must be other acceptable ways (I hope). If one user using/modifying and existing parent object while another user wishes to turn it into a child object, how would you expect the object identity to be maintained? Parent entities cannot morph into child entity objects in java, so it ...
I have code (probably seen here before) that has a ConfigurationSet and a ConfigurationBundle bidirectional @ManyToMany relationship. I am not using the cascade delete, but rather am removing the relationships manually and then deciding if I can remove an orphaned entity.

I have two tables, "games" and "players" that now have entity beans and a many-to-many relationship between them. In the database, there is a separate table "game_players" (containing the columns "game_id" and "player_id") that maintains the relationship, and is referenced by the @ManyToMany annotation. ...
Hi guys I have encountered a bug in the Hibernate Validation version that is bundled with Glassfish 3. I am trying to deploy my application with a newer version (built from source), but Glassfish won't pick it up. I also tried putting the hibernate-validator.jar in glassfish/lib and domain1/lib, but no difference. It looks like the bundled bean-validator.jar in glassfish/modules is always ...
16. JPA 2.0 Persistent Map Problem java.net
The language field of the map value is to be used as the map key. I absolutely want to avoid duplicating this in a redundant database table column. This is precisely what @MapKey is intended for, if I understand JSR 317 correctly, though there is a bit of vagueness whether or not the map value is allowed to be an embeddable ...
