+1 on Stripes. Extremely easy to setup and use - very powerfull and
performs quite well on GAE as its basically just a somewhat simple
filter/servlet and JSP with a stripes taglib though still, as I said,
powerfull.
I had to make a few adjustments to get it to serve @UrlBinding("/")
for example and
looks cool

Ok, upon further further reflection, MG is right there is an
opportunity for failure, even if MemcacheService.increment() behaves
as expected. Another description of the problem, with indentation to
distinguish the two threads:
Initial state, last value in db (and memcache) is 100
STARTING SAVE O
Upon deeper consideration, whether or not Monotonic currently could
produce dups depends on the exact behavior of:
MemcacheService.increment(java.lang.Object key, long delta,
java.lang.Long initialValue)
Unfortunately the documentation is ambiguous about what the return
value will be when Memcach
I have to correct myself on the HelloWorld-Project. It does throw an

Upon further investigation, it seems that none of the sandbox restrictions

Hello everyone.
I've an issue : I can't update a pojo object.
I have two classes : A user and a location.
A user HAS A location.
My servlet do this :
1) create a user without a location, make it persist
2) retrieve a user, set the location (for the first time), make it persist
3) retrieve a user
I've got your idea.
The '2)' way is more flexible, because using '3)' we should guarantee
that the key is complete and the key is not an ancestor for other
entities(extra constraints for the app).
So now I'm agreed with you that '2)' way is a choice.
Thanks, very much!

You can use the Datastore Admin tool available to Python apps that came with
App Engine 1.3.8 to delete data more easily:

Some interesting how-to post in App Engine for Python forum:

Hi,
You're right about 2): more efficient because only key is accessed: i/

Hello Didier
thank you for your reply, I will ask the question in your mentioned group.

Hi,
Is you Summary.html properly defined as a static file ? See how-to in
http://code.google.com/appengine/docs/java/config/appconfig.html#Static_Files_and_Resource_Files.
If not defined directly (or via a containing directory), GAE won't be
able to serve it to your application. Hence the 404.

Hi,
My understaning of Datastore based on Google BigTables is that you
can't share objects in 2 different apps (i.e using different id)
because the app id is part of the key of the entity. BigTable,
Datastore and GAD enforce a strong sandboxing based on this id.
The app id in the key is described

The cause of your issue is defined by the line "Caused by:

When you start googling this, you find quite a lot of issues related

Hi,
This is very probably a question related to Objectfify that is a
package independent, i.e 3rd party, of App Engine. You should ask it
there http://groups.google.com/group/objectify-appengine.
Question though: do you have a no-arg constructor in your class source
code ? It's required.
