The priority for me is to preserve my application ID during this
migration. My understanding is that it is impossible for an existing
app to switch from M/S to HR; a new app ID must be used. (I would love
it if my understanding is incorrect.)

I think there is an option to alias your old application id. So maybe
that's option for you?

What is the provider you have defined in the presistence.xml? Is it
org.datanucleus.store.appengine.jpa.DatastorePersistenceProvider?
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.

Yes all the datastore insert, update, delete done in the transaction

Cool idea, but I think you might want to look into GWT's code splitting. It
took me 35 seconds to download your 2.11MB file. That's going to turn off a
LOT of users. I understand that that file gets cached, but that's not going
to be the case on their first trip to your site.

You can reduce time-out issues if you paginate your query by obtaining

Nice looking site... just on casual perusal, two things jumped out at me:
1) Polish the navigation a bit more. For example, you zoom into the
map, click on a trail, click through to the trail's page, then hit the
browser back button (seems to be the only way to get back) - and
you're now zoomed o

Appengine uses servlet spec 2.4 so the compatible jstl library is
version 1.1. the jsp library
is version 2.0.
You compile w/ those locally, and yes, they are provided by the
container for production deployment
so you don't include them in your war file/directory.

Adding to Ian's suggesting, you might want to look at Query Cursors
and
pre-prepare reports ahead of time...
or pre-prepare reports iteratively, compress, store as blob and
download...

Thanks, Nichole. To fix the problem, I downgraded my version of JSTL to
1.1.2 and added the standard taglibs 1.1.2 library as well (which is what I
have a compile-time dependency on). This seems to have solved the issue
caused by the JSTL 1.2 vs. 1.1.x conflict. I should mention that I *am*st
Hi,
entity group is not useful at rollback but rather limits you to which
updates you can do: all the entities you touch in a single transaction
must be in the same entity group.
So, designing your groups properly is a key design issue in GAE to
avoid unnecessary complexity when you later need to
Huh?
As you are only able to do work in a single transactional unit-of-work
on a single entity-group, rollback must be considered "usefull".
