Hi, after doing some research and still not able to find the solution, iam posting this.
We are moving from ejbgen to xdoclet and facing an issue which is quite frustrating.
I will elaborate it as much as i can in hope to find the answer.
I have two entity beans in unidirectional 1->N relation, for some reason inserting record into child table fails and it complains about foreign key constraint (primary key of A not found).
EntityBBean has composite key, primary key of its own b_id and primary key of EntityA, a_id.
EntityABean.java:
