Problem with @Transactional (Transaction is not getting rollbacked)

[upendra sharma]

I have been using Transaction managment using spring. When i use Propagation.MANDATORY then it gives the following exception:

011-11-16 12:55:43,859 [http-8080-1] ERROR - No existing transaction found for transaction marked with propagation 'mandatory'
org.springframework.transaction.IllegalTransactionStateException: No existing transaction found for transaction marked with propagation 'mandatory'

I have three layers in my application, Action , Service and Dao Layer. I have generated the Arithmetic Exception in the Service Layer but even after using Transactional annotation , the entries in the database are not getting rollbacked. Below is the method in which exception is generated. This method belongs to service layer. The above exception can be removed if i use @Transactional in the action class then it generates the ArithmeticException but still the entries have been done in the database table. Rollback is not done. BOException and DAOException are user defined exception. Please help.

 */
	@Transactional(propagation=Propagation.MANDATORY, rollbackFor={ArithmeticException.class,BOException.class,DAOException.class})
	public boolean checkUser(LoginBean login) throws BOException, DAOException {

		boolean flag = false;
		dao.saveUser();
		int a = 10 / 0;
		System.out.println(a);

		/*if ((user.getUsername().equals(login.getUsername()))
				&& (user.getPassword().equals(login.getPassword()))) {
			flag = true;
		}*/

		return flag;

	}

}
