I'have tried to make a field of a class "unique" using different
combinations of JDO annotations. Never successfully.
Here is one of my variations:
---------------
@Uniques({...@unique(name="MYCONST_1", members={"userJID"})})
@Unique(name="MYCONST_2", members={"userJID"})
@PersistenceCapable(identityType = IdentityType.APPLICATION)
public class User
{
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Long id;
@Persistent
@Unique(name="MYUSERJID_IDX")
private String userJID;
[..]
---------------
Is there any way to apply "unique" constrain to a field of a class
using JDO annotations?
