CMR in CMP EJBs

I have two tables:
VENDOR and APIs that have a Many to Many relationship. I have a join table TPCP_APIs.
I have two CMP EJBs, one mapped to Vendor and the other to API.
I made CMR fields for each other in the two EJBs.
My question is, how can I do an insert in the join table only (without creating a new Vendor or API) ?
Can I use a create method in the Vendor
like create(vendor_id, api_id) ?
or something similar in the API EJB as in: create(api_id, vendor_id) ?
Thanks for any help !
I agree. Here's the link:
