I created an Enterprise Project and added some persistent entities and used the
verification target to check. Using NB5.5beta2 AppServer bundle.

Is there an issue with field vs. property access?

Verify failed with:

Test validity of EJB 3.0 persistence unit. This test tests validity using a
portable persistence provider.
For [ EnterpriseApplication1-ejb#EnterpriseApplication1-ejbPU ]

Exception Description: Entity class [class haug.persistent.Node] has no primary
key specified. It should define either an @Id, @EmbeddedId or an @IdClass.


The class is:
@Entity
public class Node implements Serializable {

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    private Long id;

    @ManyToOne
    private Node parent;
    
    @OneToMany(mappedBy = "parent")
    private List<Node> children;
    
    private String value;
    
    
    
    public int hashCode() {
        int hash = 0;
        hash += (this.getId() != null ? this.getId().hashCode() : 0);
        return hash;
    }

    public boolean equals(Object object) {
        // TODO: Warning - this method won't work in the case the id fields are
not set
        if (!(object instanceof Node)) {
            return false;
        }
        Node other = (Node)object;
        if (this.getId() != other.getId() && (this.getId() == null ||
!this.getId().equals(other.getId()))) return false;
        return true;
    }

    public String toString() {
        return "haug.persistent.Node[id=" + getId() + "]";
    }


    
    public Long getId() {
        return id;
    }
    public void setId(Long id) {
        this.id = id;
    }

    public Node getParent() {
        return parent;
    }
    public void setParent(Node parent) {
        this.parent = parent;
    }

    public List<Node> getChildren() {
        return children;
