Hi guys
I need implements this using hibernate annotation:

Code:

 CLASS A  --------------------- CLASS B
                     |
                  CLASS C

values :

Code:

     class C    class A    class B
      date       A_FK      B_FK  
  01/10/2010     a1          b1  
  02/10/2010     a1          b1  
  03/10/2010     a1          b1 

but when I enter all dates in the DB looks like this:

Code:

   date         A_FK      B_FK  
  03/10/2010     a1          b1  

How I can implements this using hibernate annotation and @Embedded?
Thanks.

My friends,
I need help. How I can develop it using hibernate annotation ?

Code:

public class Project(){
    private Long id ;
}

public class Item(){
    private Long id ;
}

Where relationship...
Example:

Code:

class relationship class Project    class Item
  01/10/2010          id1               id1  
  02/10/2010          id1               id1  
  03/10/2010          id1               id1
  01/10/2010          id2               id1 
  01/10/2010          id1               id2

One Item 1 with the date '01/10/2010' , '02/10/2010' and '03/10/2010' for the Project 1 and the itself Item 1 with the date '01/10/2010' for the Project 2.vice versa.
thanks.
