I need to understand under what specific circumstances the cache would not be updated. If changes are made to the db outside of JPA, via some SQL tool then of course I know that the cache will not be aware of this. (One could use timeout perhaps in this scenario.) But what does "inside of JPA" mean exactly? Don't the updates have to be made by the same EntityManagerFactory instance? Thanks for the help, Jeff Jeff W.
