I would like to define a ManyToMany association between
2 Entities A and C.
As an additional property is required in the JoinTable, I tried
to define 2 OneToMany associations involving a new entity B.
Each time I deploy on jboss-4.0.5.GA, I get this error:
org.hibernate.AnnotationException :
mappedBy reference an unknown target entity property :
com.acme.dev001.ejb.B.a in com.acme.dev001.ejb.A.bs
What's wrong in the code that follows ?
--------------- A -----------------------
@Entity
public class A implements java.io.Serializable {
@Id
private short aNo;
@OneToMany(
targetEntity = com.acme.dev001.ejb.B.class,
cascade = CascadeType.ALL,
fetch = FetchType.EAGER,
mappedBy = "a"
)
private Collection< B> bs = new ArrayList< B>();
--------------- B -----------------------
@IdClass(com.acme.dev001.ejb.BKey.class)
@Entity
public class B implements java.io.Serializable {
@Id
@ManyToOne(targetEntity=com.acme.dev001.ejb.A.class)
@JoinColumn(name="aNo", nullable=false, updatable=false,
insertable=false)
private A a;
@Id
@ManyToOne(targetEntity=com.acme.dev001.ejb.C.class)
@JoinColumn(name="cNo", nullable=false, updatable=false,
insertable=false)
protected C c;
--------------- C -----------------------
@Entity
public class C implements java.io.Serializable {
@Id
private short cNo;
@OneToMany(
targetEntity = com.acme.dev001.ejb.B.class,
cascade = CascadeType.ALL,
fetch = FetchType.EAGER,
mappedBy = "c"
)
private Collection< B> bs = new HashSet< B>();
--------------------------------------------
Thanks,
Serge
