b]Hibernate version:[/b] 2.1


Mapping documents:
I have a table which is

create table A(
id NUMBER(19,0),
name VARCHAR2(255),
primary key (id)

)

and another table
create table B(
id NUMBER(19,0),
version NUMBER(10,0),
filedName VARCHAR2(255),
primary key(id, version)

)

table A's primary key is id, table A's primary key is (id, version)

mapping file:

Code between sessionFactory.openSession() and session.close():
I want to insert data into this parent table and child table

I have a class A, class B, composite key class BKey

A test = new A();
test.setName("test");
//id does not need to set here , right? as I have class to generate id for it
session.save(test);

???what should I do here with B if I want to insert data into table B
B test= new B();
SHould I need to initiate class "BKey" ?
could mapping file do it automatically? or I should manually set here?
I could not find the answer from previous post.

If anyone could give me a sample code of above should be appreciated.
the mapping file above posted is from a nice guy in this forum. But I do not know how to initiate the class and insert into table. could anyone help?
