I am new to the concept of caching.
I am trying to clear the cache using
((JpaEntityManager) em.getDelegate()).getServerSession().getIdentityMapAccessor().invalidateAll(); ((JpaEntityManager) em.getDelegate()).getServerSession().getIdentityMapAccessor().clearQueryCache();
I do a change in the database and then trying to invoke this. But i see the same onld stale data. Can you please point me to what further steps need to be taken to clear the cache.
Thank you in advance for the help

This should work. You also need to call clear() on your
or create a new one.
In JPA 2.0 you can also just use,
Blog:Java Persistence Performance
It is sorta covered in the
JavaRanch Style Guide
subject: Clear the cache
