Joseph Hwang [http://community.jboss.org/people/aupres] created the discussion "returned values are empty!" To view the discussion, visit: http://community.jboss.org/message/621968#621968 -------------------------------------------------------------- I coded 2 entity class and joined them with @ManyToOne annotation like below - 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 ;     @Column(name="EMP_Record")     @OneToMany(fetch=FetchType.EAGER, mappedBy="member", cascade=CascadeType.ALL)     private List<Records> record;     ...getter and setter method...     public List<Records> getRecord() {        return record;     }     public void setRecord(List<Records> record) {        this.record = record;     } } - Records.java @Entity @Table(name = "info") public class Records implements Serializable {        @Id    @GeneratedValue(strategy=GenerationType.AUTO)     @Column(name = "EMP_ID")     private int i;         @ManyToOne(fetch=FetchType.EAGER, cascade=CascadeType.ALL)     @JoinColumn(name="EMP_Record")     private Members member;    @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.. } EntityManager.persist is OK. Data were inserted well. But Members.getRecord() method is problem. In Bean class I coded to return value List<Records> like below @Stateless public class MappingTestBean implements IMappingTestPort {     @PersistenceContext(unitName="MyFamily")     EntityManager em;     public List<Records> getFamilyMember(String name) {         // TODO Auto-generated method stub         Members m = (Members)em.find(Members.class, name); *// EntityManager.find() works well*         System.out.println(m.toString()); *// The method prints some value*         List<Records> records = m.getRecord(); *// getRecord() return empty value*         System.out.println(records.toString());           return records;    } } in console Joined select is executed well. [STDOUT] Hibernate: select members0_.EMP_ID as EMP1_49_1_, members0_.EMP_Name as EMP2_49_1_, members0_.EMP_Passwd as EMP3_49_1_, record1_.EMP_Record as EMP5_3_, record1_.EMP_ID as EMP1_3_, record1_.EMP_ID as EMP1_50_0_, record1_.EMP_Bank_Account as EMP2_50_0_, record1_.EMP_Hobby as EMP3_50_0_, record1_.EMP_Record as EMP5_50_0_, record1_.EMP_Phone as EMP4_50_0_ from family members0_ left outer join info record1_ on members0_.EMP_ID=record1_.EMP_Record where members0_.EMP_ID=? But records value is empty nor null. I need your advice! Thanks in advance. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/621968#621968] Start a new discussion in EJB3 at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&...]
