Hi all:
We're using GAE to develop our project, but I found I have a
performance issue, when checking the logs I found the GAE will auto-
restart every 30-60 sec.
Someone tell me this's because if the web app wasn't used much, GAE
will dispose the instances, and after that made a load request to s
Even though you're not using transactions, I think it's trying to make
the .close() call atomic (maybe with an internal implicit
transaction), failing or succeeding as a whole. And as I understand
it, entities not in the same group can be stored on separate machines
so can't be operated on atomica
You will need to use an ObjectDatastore instead of JDO if you want to
use direct references as in your example.

Hi,

Hi,
I deployed some of my GAE apps to the production server some months
ago and it worked perfectly.
Recently I haven't been using GAE but now I have to.
When I try to deploy my app to the production server I always get this
error log:

Hi Bill,
Can you send me the steps to reproduce it so I can see if I am

Yes you are right the expensive part is initializing
the EntityManagerFactory in my case. Is there any way we can improve
the performance on that.

I believe you're going to have to change this to

The User isn't serializable. Are you using the standard User class or a
custom User class?

Are you trying one-to-many or many-to-many? By using a third table it
sounds like you're trying to do many-to-many, not one-to-many.
As best I can determine, the only real way to do this in GAE is to have a
User class with a collection of string properties, containing the list of
all Work ids. I
You're using a JRE instead of a JDK. There are a couple of posts about

There's very little cost to "connecting" to the datastore. If this is an
issue, I'd look at the low-level API for anything that could be a warm-up
request. The expensive part of this is initializing your
PersistenceManagerFactory/EntityManagerFactory, not establishing a datastore
connection.

Originally, I'd thought something along the same lines, but this isn't the
case. In my running server there's no asm running in my application
classpath, environment, or lib/ext. It's only in GAE and my application.

I am stuck at precisely the same point. Which version of asm are you
