If you require complex joins in your query, then you probably have to
develop that entity bean as bean managed... That should solve your issue..
Or you can make the bean to be self-contained and one bean can make a use of
another as one to many relationship. That way, if you want to find out if
one is there in another bean, you simply use the findBy* method to see if it
returns the ref or not. If it does, then it's there...
