[appengine-java] Re: Object Manager has been closed on 2 synchronous requests
Hmm, does it really matter even when using detached objects?
And aren't the persistence managers created individually on each
request?
I didn't know they are shared over many requests?
What's the best way to update about 20 objects synchronously using 20
asynch urlfetches?
It needs to be urlfetches, because the 20 objects are getting updates
from an urlfetch again.
Simple model:
- call 20 urls with individual ids
- each url gets an objects and gets its updates from another url
Any good solution for that?
Thanks

hi,
you should only close the persistence manager when your done.
This error occurs because you try to close it a second time.
Once you do the pm.close() all the data will be updated

Hi,
I'm getting an JDO/Nucleus exception when running 2 synchronous
requests on different ids of an object:
org.datanucleus.exceptions.NucleusUserException: Object Manager has
been closed
---
This is how my getById looks like:
PersistenceManager pm = getPM();
Stream stream = null;
try {
Stream tmp = pm.getObjectById(Stream.class, id);
stream = pm.detachCopy(tmp);
} finally {
pm.close(); // here the exception occurs
}
return stream;
---
It works fine on single request, but fails on 2 or more.
anyone know how to get around this?
Thanks
