I'm new to struts2. I want to validate whether certain record exist in the DB or not. Now I dont have just a single field to validate to check duplicate record but I need to check complete recored with comibination to say data is duplicated.
What I mean is, optionId should have unique key value pair. there can be multiple key value pairs for one optionId. i'm using actionvalidation.
it seems something is missing, i can still enter duplicate data. can anyone help please?
