Hi,
I want to use value objects.
I read the xdoclet documention about value object, but when I try to use the xdoclet
@ejb.value-object tag, I get an exception :
13:27:32,103 ERROR [LogInterceptor] TransactionRolledbackLocalException in method:

My Language EJB looks like :

| * table-name = "language"
| *
| * @ejb.util generate = "physical"
| * @ejb.value-object match = "*"
| *
| */
| public abstract class LanguageBean implements EntityBean {
|
| private EntityContext _ctx;
|
| //#######################################

Note the two last methods, the first may return me the value object for this entity
EJB, but it appears that NO!!!
Can anybody help me and tell me where I can get a better documentation about the
value-object xdoclet tag use.
Thanks.
