I am much new to hibernate and i am stuck at a point.
I am trying to save nested object and out of those nested objects i dont want to save one object. How can i achive this?
When i am running this i am getting transient exception "org.hibernate.TransientObjectException: object references an unsaved transient instance". I know i am doing something stupid whihc is not recommended by hibernate. Please help.



Scenario:
A, B, C, D are four diffrent tables.

Table A ( field1, field2 , field3[fk to table B])
Table B ( field3, field4 , field5 [fk to table C])
Table C ( field5, field7 , field8)
Table D ( field6, field9 , field3[fk to table B])


Objects

A
private String field1;
private String field2;
@OneToOne(cascade=CascadeType.ALL)
@JoinColumn(name="field3")
private B b;


B
private String field3;
private String field4;
/*Want to save D*/
@OneToOne(cascade=CascadeType.ALL)
@JoinColumn(name="field3")
private List<D> d; // This is a list of D
/*Dont want to save C*/
@OneToOne
@JoinColumn(name="field5")
private C c;

C
private String field5;
private String field7;
private String field8;
D
private String field6;
private String field9;
private String field3;
