                BeanUtils.copyProperties(temp, tempCustomers);


                tempCustomer.add(temp);
                getEntityManager().persist(temp);

            }catch (Exception e) {
                // TODO: handle exception
                return "null";
            }

             }
            log.info("Size........."+tempCustomer.size());
            return "null";
    }

@Begin(join = true)
    public String updatedData(){
         log.info("Size of Customers :"+tempCustomer.size());
         log.info("Decision ..."+decision);

        try{    
       if(decision.equals("Continue")){
        for(TempCustomers tempCust:tempCustomer){

            TempCustomers temp=new TempCustomers();
            BeanUtils.copyProperties(temp, tempCust);   

            log.info("updated Sucessfully");

           getEntityManager().getTransaction().commit();

       }}else{
           getEntityManager().getTransaction().rollback();

        }
        }
        catch(Exception e){

        }
}

please help me how to do continue and rollback in jpa with hibernate when getEntityManager().persist() is done.

Answer 1

To commit with JPA:

entityManager.getTransaction().commit();

To rollback with JPA:

entityManager.getTransaction().rollback();

Call either of these methods after your call to persist to perform the desired action. In your case entityManager would be replaced with the call to retrieve the entityManager, getEntityManager()
