TransactionRequiredException Executing an update/delete query

Question

Hi I am using hibernate JPA with spring and mongodb and i am running my application on Glassfish-4.0.

My service class is :

@Component
public class T         


        

Answer 1

I was facing the same error inspite of adding @Transactional annotation at class level and importing org.springframework.transaction.annotation.Transactional.

Then I realized that since I was using hibernate query, I had imported javax.persistence.Query instead of import org.hibernate.query.Query. Therefore adding import org.hibernate.query.Query solved the issue for me.

I hope this idea helps someone.
