What is the EclipseLink's equivalence of Hibernate's @NotFound annotation?
0
With my legacy db, some fields map for other table's PK without FK information and defined as not-nullable.
class SomeChild {
private long parentId; // No FK, 0 for none.
}
With hibernate, I think, I can do this.
class SomeChild {
@NotFound(action=NotFoundAction.IGNORE)
@ManyToOne
private Parent parent;
}
How can I do this with EclipseLink?

Not sure I understand. How would you insert 'someChild' in such a case? Regardless, seems you are better off mapping that parentId as a basic AND use it in the manyToOne, but make the ManyToOne read-only so there isn't any confusion when one is null and the other 0.
