Trouble with two tables and persistence

Question

Hi all,
I would need your opinion on this:
I have two tables:
Table User (UID(PK), Uname, Pword)
Table Choice (CID(PK), UID(FK), Cname, Cparameter1, Cparameter2)
I have tried to put both together into one entity as described in: http://en.wikibooks.org/wiki/Java_Persistence/Tables#Example_mapping_annotations_for_an_entity_with_multiple_tables
However, the trouble is that it doesn't work as I have hoped. I am unable to insert data into the user table alone, because it complains about missing entries for CID, Cname, etc...). I thought I would be able to query them independently, as 1 user can have many Choices.
Any suggestions how to tackle this problem?
Thank you.

Ahh, I think I have figured out part of it but it isn't working yet. I created a view of the trk_user table. Now I need help with the code, I am trying to incorporate it here:
SELECT webb.TRK_CALLS_VIEW.ID, webb.TRK_CALLS_VIEW.USER_, webb.TRK_CALLS_VIEW.ASSIGNED_TO, webb.TRK_CALLS_VIEW.PROBLEM, webb.TRK_CALLS_VIEW.SOLUTION, webb.TRK_CALLS_VIEW.STATUS, webb.TRK_USER_VIEW.lname, webb.TRK_USER_VIEW.fname
FROM webb.TRK_CALLS_VIEW, webb.TRK_USER_VIEW
WHERE
( STATUS = 'Open' and :P2_REPORT_SEARCH is null )
or
( regexp_like( USER_ || '#' || ASSIGNED_TO || '#' || PROBLEM || '#' ||
SOLUTION || '#' || STATUS, :P2_REPORT_SEARCH, 'i' ) )
Can someone help me in the right direction
