Hibernate version:
2.1.6

I have class A with an attribute of type B, and a setB() method in A. There is a many-to-one relation between A and B. I need to save an instance of A, and I would like to do a setB() with a new object B, not read from the DB (for performance reason).
I know the primary key of B and I've set it, but when I save A, I get a TransientObjectException.
Is there a way to avoid reading B from the DB, without changing the mapping? (This is a tool that do this job on many classes, and I do not know the structure of these classes).
Any suggestion will be greatly appreciated.

I solved the problem in this way

Created a new Object of class B, set the primary key and the attribute mapped as <version ...>. The value for this last attribute is meaningless.
If anyone need to do something like this.

I'm having the same problem, can you explain a little more how you resolved your problem using <version ...> In particular, could you share the relevant parts of your mapping files?

Thanks,
Jed

I've mapped a field named countUpd as <version> like this:

<version
"column" = "count_upd"
"name" = "countUpd"
"type"= "long"
/>

and then to save the object A I write something like:

b.setPrimaryKey(val);
b.setCountUpd(new Long(0));
a.setB(b);
a.save();

Hope this helps
Bye

If you enable lazy="true" for you class, Hibernate probably won't load the object from the database in this case. So you could do:

a.setB(session.load(123));
session.save(a);
