Hi list,

I have two class, SimplePrincipal and SimpleUser, their relationship
and java code with annotation list below:

@Persistent
public class SimplePrincipal {
@PrimaryKey
private String name;
......
}

@Entity
public class SimpleUser extends SimplePrincipal {

/**
* The profile properties.
*/
@SecondaryKey(relate=ONE_TO_ONE)
private Map properties;
}

The above code doesnot work since Map is complex object type. So now I
give one fake field as SecondayKey. Any other solutions to handle this?

Hello Jack,

I posted your question to the Berkeley DB Java Edition discussion forum
and have asked you for more information in that message:

Sorry, I meant "use the product forum" not "use the product".

Hi Mark,

The integrated SimpleUser should own two attributes <name, properties>,
and I just want to retrieve SimpleUser via name(it is unique).
