Only one thing I can do NOW to pass the test is modify the Product class: 1) Make Image setter non-public. 2) Change image via method. That will: 3) Retrieve the Session (via ServiceLocator). 4) Delete old Image. 5) Assign the new Image.
Is it the only way of oding it? Is it really impossible to do handle this via mapping?
