Re: [eclipselink-users] Updates on Database not being picked up via eclipselink 
If you never what to cache, then I would recommend @Cache(shared=false)
instead of alwaysRefresh (means don't use a shared cache, instead of use a
shared cache but keep refreshing it).  But alwaysRefresh will work as well.

If you want to cache, then just call refresh() when you really need to, or
set the Query refresh hint.
