Re: [eclipselink-users] Newbie mapping question

Hi,
Your mapped by is incorrect and should be specified as follows:
mappedBy="relateda"
And your JoinColumn is inversed. It should be
@JoinColumn(name="Akeyname", referencedColumnName="Bkeyname")
Cheers,
Guy

Subject: [eclipselink-users] Newbie mapping question
Hi to everybody.
My project works on two entities with a "one to many" relation.
A entity defines a collection of B elements as described here :
@OneToMany(cascade = CascadeType.ALL, mappedBy = Bkeyname, fetch =
FetchType.EAGER)
private Collection bcollection;
And B relates to A like this:
@JoinColumn(name = Bkeyname, referencedColumnName = Akeyname)
@ManyToOne
private A relateda;
Fetch = FetchType.EAGER should grant me that every "find" operation
on A should retrieve every B entity related to A, am i wrong?
This is not happening in my project! I always see null values on B
collection,
what am i doing wrong?
Thanks in advance
