Hi Armin, Brain and the rest :-)
hier is my code (a simple test-example)
CAR:
package de.ralle;
import java.io.Serializable;
//the CAR
public class Auto implements Serializable{
private String farbe;
public Auto() {
}
public String getFarbe() {
return farbe;
}
public void setFarbe(String string) {
farbe = string;
}
}
CUSTOMER:
package de.ralle;
import java.io.Serializable;
//my customer!
public class Kunde implements Serializable{
private String vorname;
private String nachname;
private Auto auto;
public Kunde(){
}
public Auto getAuto() {
return auto;
}
public String getNachname() {
return nachname;
}
public String getVorname() {
return vorname;
}
public void setAuto(Auto auto) {
this.auto = auto;
}
public void setNachname(String string) {
nachname = string;
}
public void setVorname(String string) {
vorname = string;
}
}
and XML:
<class-descriptor
class="de.ralle.Kunde"
table="Kunde" >
<field-descriptor
id="1"
name="id"
column="id"
jdbc-type="INTEGER"
primarykey="true"
access="anonymous"/>
<field-descriptor
id="2"
name="vorname"
column="vorname"
jdbc-type="VARCHAR"/>
<field-descriptor
id="3"
name="nachname"
column="nachname"
jdbc-type="VARCHAR"/>
<field-descriptor
id="4"
name="autoId"
column="autoid"
jdbc-type="INTEGER"
access="anonymous"/>
<reference-descriptor
name="auto"
class-ref="de.ralle.Auto"
auto-retrieve="true"
auto-update="true"
auto-delete="true">
<foreignkey field-ref="autoId"/>
</reference-descriptor>
</class-descriptor>
<class-descriptor
class="de.ralle.Auto"
table="auto">
<field-descriptor
id="1"
name="id"
column="id"
jdbc-type="INTEGER"
primarykey="true"

</class-descriptor>
THANKS!
