I solved org.hibernate.TransientObjectException (http://community.jboss.org/thread/171019?tstart=0) 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*

@Table(name = "family")
public class Members implements Serializable {
  @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 (http://community.jboss.org/mailto:%7B@JoinColumn(name) = "EMP_Name")})
  private Collection<Records> record = new ArrayList();
   ....getter and setter

*- Records.java*

@Table(name = "info")
public class Records implements Serializable {

  @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();

Members m = new Members();

port.setFamilyMember(m); // This EntityManager.persist method

But it failed.

In console
20:21:29,233 INFO [STDOUT] Hibernate: insert into family (EMP_Name, EMP_Passwd, EMP_ID) values (?, ?, ?)
20:21:29,268 INFO [STDOUT] Hibernate: insert into info (EMP_Bank_Account, EMP_Hobby, EMP_Name, EMP_Phone) values (?, ?, ?, ?)
20:21:29,288 WARN [JDBCExceptionReporter] SQL Error: 1364, SQLState: HY000
20:21:29,288 ERROR [JDBCExceptionReporter] Field 'record_EMP_ID' doesn't have a default value

record_EMP_ID is automatically generated by hibernate

Pls help!
