Hi Yasuo,
The maximum number of entities in a batch put or batch delete is 500.
The maximum number of entities in a batch get is 1000.
That's true, but in this case I'm assuming not all keys have entries
so I'll only get back the entities that exist. They keys that have no
associated entities

I'll be happy to share the code as soon as it is running smoothly and
I got rid of the above mentioned AccessControlException.
Thus, I hope somebody could give me a hint what is causing the

I did more or less the same thing for the same reasons, and with the same

generate my model from an RDBMS. This way I know I can port my app to an

Hello,
Since about 15 mins ago, when I try to update my application, it is
returning an error 500 (internal server error) and if i try again,
error 409 (conflict) until I restart my eclipse, then it goes back to
error 500 once and then 409 again.
Did something happen and my application got
The 500 errors in the Admin Console are a general issue that we're looking
into.
The 409's indicate that you have a pending update that needs to be rolled
back (via appcfg.sh rollback) due to one of the 500 errors. After rolling
the update back you can try to deploy again.

I can not make my question more specific because I totally have no idea on

Can I say we just
query.setFilter(key == :keyList);
ListMaster list = (ListMaster) query.execute(keyList);
I'd like to know if that works with GAE/J, because it is illegal JDOQL
syntax and would be a bug. JDOQL is supposed to follow Java syntax,
and you simply cannot do
Key == ListKey
and get success in Java.
