I'm trying to map a one-to-many relation.

the point is I'm sending a composite pk from the one to the many side.

On the many side, I can map both PK columns in a single XDoclet TAG.

But I can't (actually nobody here can) figure out how to send both columns from the one side.


I'm using an @hibernate.set where the columns are declared as:
@hibernate.composite-key
column=<column name>
@hibernate.composite-key
column=<column2 name>

But the second one will never be mapped to the hbm.xml file by the ant.

Can someone teach us how to build this one-to-many-with-a-composite-key in the pojos? And tag it in a way it will be mapped to the hbm.xml file by the ant?

From memory YMMV.

@hibernate.set lazy=true
@hibernate.collection-key column=col1
@hibernate.collection-key column=col2

Thanks. Actually, I found out that the ant won't build the relation correctly from that statment. It'll put only one of the two columns in the hbm.

I read in a tutorial I found that it should be:

@hibernate.collection-key
@hibernate.collection-key-column
name="NAMEOFTHECOLUMN"
@hibernate.collection-key-column
name="NAMEOFTHEOTHERCOLUMN"

At least it works with this one. But somehow the ant that builds the schema (and the tables in the oracle base) is pointing out it can't find the class's PK
and, acording to the references I have, everything should be right.

The pk POJO has the hash and equals it needs, and also the path the program claims it can't find the file into is right too.

Traditionally, only separate composite key classes are supported. Integrated is not. Obvious, hibernat expects the order to be the same as well.
