Hi, I had a problem where I was using the hibernate template to do most of my DB work but I had a part of the system that directly accessed the session to do batch persisting. I noticed that the hibernate template session was old and would be storing cached values which didnt take into account the objects save with the session directly. ...
I have the following method and want to avoid having to explicitly show the JAXBElement<> syntax.
