If a Primary key maps to multiple fields in the Entity bean class then how is the <primkey-field> specified in the deployment descriptor.

The primkey-field element is not used if the primary key maps to multiple
container-managed fields.
You will use the <prim-key-class> for compound keys.

I am still confused.
What if there are 3 fields in the database which are of type String and I want to used 2 of the fields as compound primary key.
How will I mention that in the deployment descriptor using <prim-key-class>

you will make a new class with the two fields as its instance variables and write that class name in the <prim-key-class>
