[jboss-user] [Beginners Corner] - Improper relationship betrween Entity-Beans
Hello out there,
I created for my small project two Entity-Beans which have a 1toN-relationship. In detail
I have one ZugangsdatenBean (this is german but it doesn't matter what this means) and
several TanBeans. From my point of view, there should be no problems. I show you the two
beans. First the ZugangsdatenBean which is on the '1'-Edge:
@Entity
| @Table(name="ZUGANGSDATEN")
| public class ZugangsdatenBean implements Serializable
| {
| private static final long serialVersionUID = 1L;
| private String passwort;
| private String login_Name;
| private String pin;
| private Collection <TanBean> tans = new ArrayList<TanBean>();
|
| public ZugangsdatenBean() {}
|
| public ZugangsdatenBean( String passwort, String login_name, String pin )
| {
| this.passwort = passwort;
| this.login_Name = login_name;
| this.pin = pin;
| }
|
| @Column (name="PASSWORT")
| public String getpassword()
| {
| return this.passwort;
| }
|
| public void setpassword(String mypassword)
| {
| this.passwort = mypassword;
| }
|
| @Column (name="LOGIN")
| public String getlogin_name()
| {
| return this.login_Name;
| }
|
| public void setlogin_name(String mylogin)
| {
| this.login_Name = mylogin;
| }
|
| @Id
| @Column (name="PIN")
| public String getpin()
| {
| return this.pin;
| }
|
| public void setpin(String mypin)
| {
| this.pin = mypin;
| }
|
|
| @OneToMany (mappedBy="zugangsdatenbean",cascade=CascadeType.ALL,
fetch=FetchType.EAGER)
| public Collection <TanBean> getAllTans()
| {
| return this.tans;
| }
|
| public void setTans(Collection <TanBean> mytan)
| {
| this.tans = mytan;
| }
|
|
| }
| And now the TanBean:
@Entity
| @Table(name="TAN")
| public class TanBean implements Serializable
| {
| private static final long serialVersionUID = 1L;
| private String nummer;
| private ZugangsdatenBean zugang = null;
|
| public TanBean (String mynummer)
| {
| this.nummer = mynummer;
| }
|
| @Id
| @Column (name="TNUMMER")
| @GeneratedValue ()
| public String getNummer()
| {
| return this.nummer;
| }
|
| public void setNummer(String mynummer)
| {
| this.nummer = mynummer;
| }
|
| @ManyToOne
| @JoinColumn(name="ZUGANGSDATEN")
| public ZugangsdatenBean getZugangsDaten()
| {
| return this.zugang;
| }
|
| public void setZugangsDaten(ZugangsdatenBean myzugang)
| {
| this.zugang = myzugang;
| }
| }
|
The Eclipse-Console give me this errors:
23:52:14,124 WARN [ServiceController] Problem starting service
persistence.units:ear=TestBank.ear,jar=TestBankEJB.jar,unitName=chaos
| org.hibernate.AnnotationException: mappedBy reference an unknown target entity
property: org.chaos.tans.TanBean.zugangsdatenbean in
org.chaos.zugangsdaten.ZugangsdatenBean.allTans
What is my misstake?
Than you
Gruss Christian
