Hi all,
I'm facing some problems trying to remove an entity from the database.
I have an interface to abstract the AppEngine Entity from my business
Object. I can easily Insert and Update, but when I try to delete I got
the error:

Hi all,
I'm new in JPA / JDO and I'm totally sure I'm doing something wrong. I
don't know why I can't see children objects in the same transactions using
the same PM

What is the provider you have defined in the presistence.xml? Is it

The missing class, ProviderUtil, is from JPA 2.0. Since Google
provides JPA 1.0, it is not so surprising that the class can not be
found.

Hi Dimitar,
This is an idea. Take a closer look to your _ah_SESSION kind. It is
possible you are storing huge session data and it remains there after
the sessions expire. If that is the case, you probably want to clean
your expired sessions periodically.

Hi Mike,
You may want to see the "Selling App Engine Apps" thread in the Google
App Engine group. The 3rd post, by Brian Flood, explain his approach
to your question and it is pretty cleaver.

Ikai,
Me too I can report an improved response time and no datastote timeout
exceptions the past couple of days. I have no measurements so far, but
the improvement is noticeable. I'll certainly keep watching and let
you know of any relevant issues.
Thanks!

I found another issue with the /_ah/sessioncleanup servlet. On almost
every run, a huge amount of cpu usage is reported!
Example:
01-08 07:40AM 53.487 /_ah/sessioncleanup?clear 200 12275ms 7365cpu_ms
3845api_cpu_ms 0kb

The /_ah/sessioncleanup servlet works ok, but it cleans only 100
expired sessions at a time, so one needs to run it often enough to
avoid expired sessions to accumulate and no so often that it won't
have too few sessions to purge.
Kind of complicated!!
Someone knows of a better solution?
Is there a way to delete old _ah_SESSION entities? I found a post
about deleting all sessions, both from the datastore and from
memcache, but I am looking a clean way to delete past sessions and
preserve the active ones.
Thanks,
Jorge Gonzalez

As far as I know, Swing classes won't work with GWT. That is, those
classes won't compile to JavaScript.
On any case, you should be checking in the GWT forum rather than in
this one.

My GAE logs are timestamped with a -0800 offset. Is there a way to
control the offset? For instance, I'd prefer my logs -0600 (my local
time) or - (UTC). How/Where would I configure that?

A GAE app may have nothing to do with Google Apps. I think David's

Hello Collin,
That is not important, as your IDE will point to the path where the
SDK is and you don't need to worry about after that. This is what I
used in a Win XP:
C:\Program Files\Google\appengine-java-sdk-1.2.6\

Yes, the JDO classes will be automatically enhanced at the time you
start the development GAE server.
BTW, I'm also used to NetBeans rather than Eclipse and I hope the GAE
and GWT plugins for NetBeans will be further developed!

Hi Jason,
I am retaking this thread because I am experiencing the same "Caused
by: javax.jdo.JDOFatalUserException..." issue. I'm not using other
frameworks than GAE. The IDE I'm using is NetBeans and I'm using Java.
The PMF singleton is in place, just like explained in
