BD really is Data Base ( excuses, I said it to you in Spanish...)...
I am using JDO but he says a mistake to me saying that
I have to form the files xml. In that folder I must put them?
With that it names? Example?
The headlines of the classes(This me does not work):
@PersistenceCapable(identityType =
IdentityType.APPLICATION,detachable="true")
@Inheritance(strategy = InheritanceStrategy.SUBCLASS_TABLE)
public class RegFechaUsuario extends Fecha implements Serializable {
(Key does not have, not if this is nice)
....
....
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable = "true")
public class Fecha implements Serializable {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key id;
.....

Lisandro
