i trying setup 1 many relationship using hibernate/jpa.

currently getting exception:

i know making mistake in @onetomany or @manytoone annotation.

update: have 2 tables in db, refund_transaction , item_refund_detail. , dont't have table named refund_transaction_item_refund_detail. after normalizing schema, have added refund_request_id in item_refund_detail table maintaining relationship. need maintain unidirectional mapping, achieve this. please advice.

you're doing many things wrong. of points:

1. you're using both field , property access. have pick 1 style default (you can override default accesstype desired properties).
2. @elementcollection used embedded collections, hence error get. should use @onetomany this.
3. don't forget declare 1 side of bidirectional association inverse 1 (in case of @onetomany relation, that's entity on one side).
