I solved org.hibernate.TransientObjectException by adding "@OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL)"
But this time values can't be inserted to DB.
OS : Windows 7
JDK : JDK 1.6
JBoss : JBoss 5.1.0.GA
DB : MySQL 5.5
Error is "Field 'record_EMP_ID' doesn't have a default value"
- Members.java
@Entity
@Table(name = "family")
public class Members implements Serializable {
@Id
@Column(name = "EMP_ID")
private String id ;
@Column(name = "EMP_Passwd")
private String passwd ;
@Column(name = "EMP_Name")
private String name ;
@OneToMany(fetch=FetchType.EAGER, cascade=CascadeType.ALL)
@JoinTable(name="info", joinColumns = {@JoinColumn(name = "EMP_Name")})
private Collection<Records> record = new ArrayList();
....getter and setter
}
- Records.java
@Entity
@Table(name = "info")
public class Records implements Serializable {
@Id
@GeneratedValue(strategy=GenerationType.AUTO)
@Column(name = "EMP_ID")
private int i;
@Column(name = "EMP_Name")
private String name;
@Column(name = "EMP_Bank_Account")
private String account;
@Column(name = "EMP_Hobby")
private String hobby;
@Column(name = "EMP_Phone")
private int phone;
...getter and setter method
}
in jsp file I invoke EntityManager.persist
Context ctx = new InitialContext();
IMappingTestPort port = (IMappingTestPort) ctx.lookup("MappingTestBean/remote");
Records r = new Records();
r.setName("aaa");
r.setAccount("111-2222");
r.setHobby("bbb");
r.setPhone(021112222);
Members m = new Members();
m.setId("aupres");
m.setPasswd("aaa");
m.setName("ccc");
m.getRecord().add(r);
port.setFamilyMember(m); // This EntityManager.persist method
But it failed.
In console

Pls help!
