SecondaryTable to map an array attribute ot a class.

[chornsey]

In Hibernate 3 defining a class with an array could be mapped quite easily.

Lets say I have the following class

public class Entity
private int ID;
private String val1;
private String val2;
private String val3;
private String[] codes;
........

The following tables are used to persist this class:
ENTITY
ID int,
val1 VARCHAR(25),
val2 VARCHAR(25),
val3 VARCHAR(25),

ENTITYCODES
ENTITY_ID int (FK to ENTITY.ID),
Code VARCHAR(5)

Mapping this in hibernate thrree is very simple this is an example config file for Entity:






I thought I could use the SecondayTable annotation in EJB3 to accomplish the same thing. Does anyone know how to accomplish this type of mapping with EJB3 annotations?

Check the latest Hibernate Annotations doc, there is an example on how to map an array of primitive type. Note that this is not considered portable, though.

This is a hibernate 3.1 extension. How can I use hibernate 3.1 in an ejb3 server. The ejb3 deployer has hibernate 3 jars. Can I just replace these jars with the 3.1 jars?

For anyone else you must be using EJB3.0 RC2 in order to use this hibernate annotation.
