This week's book giveaways are in the Refactoring and Agile forums. We're giving away four copies each of Re-engineering Legacy Software and Docker in Action and have the authors on-line! See this thread and this one for details.
I`m a little bit confused at page 304 of the EJB3 in action with the code below
The purpose of the code is to undo the changes made on the item, so why don't we just say entityManager.refresh(item), insted of passig again the entityManager.merge(item) as an argument to the refresh method ??
It's the same thing with the second method when it comes to deleting an item ( why domn't we just say entityManager.remove(item) instead of entityManager.remove(entityManager.merge(item)) ??
