Hi Julio. Can you clarify what you mean by this statement: "If i change the code to the mail handler class, it works."
As Andy says, creating a new PersistenceManager isn't very expensive, so I wouldn't store an instance in a static variable or worry about sharing an instance with other classes -- just create one when you need it and close it as soon as you're done. You should, on the other hand, make sure to only load one PersistenceManagerFactory. I see you're using a static variable, but you can also use a singleton: http://code.google.com/appengine/docs/java/datastore/usingjdo.html#Getting_a_PersistenceManager_Instance Please make sure you're closing your PersistenceManager after every datastore operation -- I notice that you have commented out a few of your close() calls in a few places. For what it's worth, this is what a typical method in my own DAO looks like: public void storeEvent(Event event) { PersistenceManager pm = PMF.get().getPersistenceManager(); try { pm.makePersistence(event); } finally { pm.close(); } } - Jason On Fri, Oct 30, 2009 at 4:36 PM, Julio Faerman <[email protected]> wrote: > > Here is what the log reads: > > 22:29:41,776 DEBUG [DataNucleus.Persistence] - Making object > persistent : "br.com.ximp.vike.server.model.games.ww.ac...@d4ddfd" > 22:32:02,701 DEBUG [DataNucleus.Persistence] - ObjectManager > internalFlush() process started - 1 dirty objects > 22:32:02,701 DEBUG [DataNucleus.Persistence] - ObjectManager > internalFlush() process finished > 22:32:02,702 DEBUG [DataNucleus.Persistence] - Disconnecting > br.com.ximp.vike.server.model.games.ww.ac...@d4ddfd from StateManager > [pc=br.com.ximp.vike.server.model.games.ww.ac...@d4ddfd, > lifecycle=P_NEW] > 22:32:02,703 DEBUG [DataNucleus.Persistence] - Object Manager > "org.datanucleus.objectmanageri...@1d4c2ba" closed > > But the object (ac...@d4ddfd) is not persisted on PM close. > > On Oct 30, 5:10 pm, datanucleus <[email protected]> wrote: > > > - No error is logged > > > > As I already said, the log would tell you what happens.
