Actually, my librarie contains a servlet, but it is not called when I
request the url-pattern, so I have a 404 Error. It works fine in a
Eclipse Web Project, but not in Google Web Application Project.

I have in my DataStore an entity 'Page' with fields :

I would like to fetch pages with only some tags, something like that :

Hi,
it's going to be a little bit hard with Google only: the same cookie

I would guess that you have to "surimpose" your own layer of
application to manage such a separate login process.
Google is testing mutiple logins but - to my knowl

Thank you for the quick response. However it is said that files in WAR

that I can create a directory at runtime in the /war directory? Or the

I've got a problem with an application developed in Clojure. When I

when I upload it I get a VerifyError during startup. Here's a

You can try to update counts on write, but this will only work for queries
you know apriori. Even a count on keys isn't great - we need to run through
all the indexes that match the query.

Just use an equality filter - this should work just fine.
Select from Kind where propertyName contains 'propertyValue' is just:
Query q = new Query("Kind");
query.addFilter("propertyName", FilterOperator.EQUAL, "propertyValue");

Not that it should matter, but are you on the newest SDK?
Can you post a screenshot of AppStats? It's my understanding that the blog
post is out of date. They should be happening in parallel. You're not going
to save that much CPU time, though, since it still takes CPU to save all the
entities (bu
So I wrote:
Query query=new Query("page");
query.addFilter("tags", FilterOperator.EQUAL, "sport");
query.addFilter("tags", FilterOperator.EQUAL, "video");
and i obtain the query :
SELECT * FROM page WHERE tags = video AND tags = sport
It was too easy : ).
Thank you Ikai Lan
They're a function of the datastore itself, but they don't create indexes or
any of the things that are usually associated with entity writes. The worst
case performance has allocateIds doing a write to a hard disk, but most of
the time they retrieve data from in-memory caches.
What are you trying
Ikai,
Thanks for your prompt reply. I do not know the queries apriori.
I am using JDO.. Can I use batch get for JDO queries?
This saves me a round trip to the data store.

Hi,
I must admit that my db knowledge is very lacking, thus I need some
help with making a simple query. I know I am just missing smth obvious
and easy.
Anyway, what I need is just a boolean method to check if enity
exists.
I am using Guice too, for binding all stuff.
I know that the query synt
I don't see how this could work without updating the deployed image.
What I mean is that if one deployed instance was able to create the
directory or alter any of the files in the deployed image, none of these
changes are replicated to other deployed instances.
Perhaps you can script the file sys

Well it seems like after the query, if I call em.clear() everything seems to
work fine. Note that my initial query was only returning a list of IDs, not
entity objects but it looks like app engine still caches the entity objects
in the first level cache. When the subsequent transaction is opened an
