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

In my case, I had the wrong @Transactional imported.

The correct one is:

import org.springframework.transaction.annotation.Transactional;

and not

import javax.transaction.Transactional;
