Hi,
Let us assume a fragment of domain model
public class Student {
private Map<Course, Semester> enrollment;
}
The following query (that involves a predicate on the keys of the map)
will return the Students who enrolled for a course named ':name':
"select s from Student s JOIN s.enrollment e where
KEY(e).name=:name";
