Hi,
when I call and oABean.getBBeans(), on an ABean loaded from DB,
I obtain a "null" Set [on DB exist a C-record which link loaded
A-record with B-records]. Any Idea?
package test.ejb.entity;
import java.util.*;
import javax.persistence.*;
import javax.ejb.*;
@Entity
@Inheritance
@Table(name="a")
@NamedQuery(
name="ABean.findAll",
query="SELECT o FROM ABean o ORDER BY o.m_sInfo DESC"
)
public class ABean { //extends IdEntityBean {
@Id
@SequenceGenerator(name = "ASeq", sequenceName = "a_id_seq")
@GeneratedValue(strategy = GenerationType.AUTO, generator = "ASeq")
Integer id;
public Integer getId() { return id;}
@Column(name="info")
String m_sInfo;
@PrePersist
public void setCreateInfo() {
m_sInfo = "";
}
public String getInfo() { return m_sInfo;}
public void setInfo(String info) { m_sInfo = info;}
// table "c": link A<->B
@ManyToMany
@JoinTable(name="c",
[EMAIL PROTECTED](name="idA")},
[EMAIL PROTECTED](name="idB")}
)
Set BBeans;
public Set getBBeans() { return BBeans;}
public void setBBeans(Set BBeans) { this.BBeans=BBeans;}
}
TIA
