Hey,

could you tell me what is wrong with this code:

first class:
package test.beans;

public class Bean1 {

private long bean1id;
private String value;
private Bean2 bean2;


public Bean2 getBean2() {
return bean2;
}
public void setBean2(Bean2 b2) {
this.bean2 = b2;
}
public long getBean1id() {
return bean1id;
}
public void setBean1id(long bean1id) {
this.bean1id = bean1id;
}
public String getValue() {
return value;
}
public void setValue(String value) {
this.value = value;
}

}

second class:
package test.beans;

public class Bean2 {

private long bean2id;
private long bean2bean1id;
private double price;

public long getBean2bean1id() {
return bean2bean1id;
}
public void setBean2bean1id(long bean2bean1id) {
this.bean2bean1id = bean2bean1id;
}
public long getBean2id() {
return bean2bean1id;
}
public void setBean2id(long bena2id) {
this.bean2bean1id = bena2id;
}
public double getPrice() {
return price;
}
public void setPrice(double price) {
this.price = price;
}
}

and main class:
package test;


import org.hibernate.Session;
import org.hibernate.SessionFactory;
import org.hibernate.cfg.Configuration;


import test.beans.Bean1;
import test.beans.Bean2;

public class MyClass {

public static void main(String[] args) {

a.go();
}

private void go() {
SessionFactory sf = new
Configuration().configure().buildSessionFactory();
Session session = sf.openSession();

session.beginTransaction();

Bean1 b1 = new Bean1();
b1.setValue("test");

Bean2 b2 = new Bean2();
b2.setPrice(12.12);

b1.setBean2(b2);
session.save(b1);

session.getTransaction().commit();

}

}


Be nicer if you told up what your error is..
