[news.eclipse.rt.eclipselink] @ManyToOne relation problem

[montes.benoit@xxxxxxxxx (Benoit Montes)]

Hi,

I have a dilemma:

+ I have 2 entities with a ManyToOne relationship and no unique ids 
(Embedded ids):

Entity A (date, field1, field2)
Entity B (field1, field2, startDate, endDate)

+ Primary key of Entity B is an embedded id composed by field1, field2, 
and startDate.

+ Relationship between EntityA and EntityB

SELECT EntityB.*
FROM EntityA, EntityB
WHERE EntityB.field1 = EntityA.field1
AND EntityB.field2 = EntityA.field2
AND EntityB.startDate <= EntityA.date
AND EntityB.endDate > EntityA.date

It always return an unique row.

=> Is it possible to establish the relationship between EntityA and Entity B 
with JPA annotations to fetch EntityA rows or I need to use a JPQL query to 
make the join ?
