No identifier specified for entity in java hibernate

Question

I am using hibernate and i mapped my table with my bean. If i am not assign any particular column value as @id, it throws "No identifier specified for entity" error, however it is not primary key in my data table. I want to add multiple records with same data. how can i do it? When i annotated my product Name column with @id my code runs perfect.

Hibernate requires an identifier for each entity. However, it is possible to use native queries to insert new records. And, in the same way, to recover them.
