Hi,
I am new to Persistence. I would like to know is there restrictions in
the declaration of EntityManger and EntityManagerFactory in the class, ie can I
declare it as an instance variable or should I declare it locally on each
method and after the operation performed should I close it? Is there any
performance issue or any other problems in doing so? Can anybody give a
solution. The solution to this will be greatly appreciated.
Thanks,
Sreejith
