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

Nothing seemed to work for me until I realized that my method was declared as public final instead of just public. The error was being caused by the final keyword. Removing it made the error go away.
