[Beginners Corner] - Newbie problem with persitence
by stareagle
Hello,
I have a problem with the persitence in my first JBoss application. There two Beans, which have an 1:n relationship.
The problem: When I'am deploying the application, JBoss complains that I'am trying to use the OneToMany annotation on a none collection:
org.hibernate.AnnotationException: Illegal attempt to map a non collection as a @OneToMany,...
The relevant code from the class:
@OneToMany(mappedBy = "employer", cascade = CascadeType.ALL)
| public Vector<User> getEmployees() {
| return this.employees;
| }
|
| public void setEmployees(Vector<User> employees) {
| this.employees = employees;
| }
The attribute employees is a java.util.Vector. I'am very sure that a Vector is a Collection. I also tried other classes like LinkedList with the same result.
Can anybody help me?
Greetings
Stareagle
