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
