composite-id (promary key and foreign key)

I have 3 tables

Table1(IDTB1,NAME)PK->IDFIELD

Table2(IDTB1,IDTB3,OPTION) PK(IDTB1,IDTB3) FK(IDT3) references Table3(IDT3)

Table3(IDTB3,TIPO)PK->IDTB3

I would like how to know write mapament O/R for table 2 ,I don't use annotations but xml for mapament O/R .
Other .

Another thing a composite key become a class ?

There is any example this mapament?

Yes, you have to map composite key in a class.

I've a similar situation (posted here: https://forum.hibernate.org/viewtopic.php?f=1&t=997141&p=2412341#p2412341) and I think to have found an hibernate bug in mapping composite id in one-to-many relationship.
