this seems really simple but I haven't gotten this to work. I am building my app with grails on google app engine. This pretty much requires you to use JDO.
I am making an HTTP call from flex to my app. The action that I am calling on the grails end looks like so
def returnShowsByDate = {
def query = persistenceManager.newQuery( Sh...

Hey guys,
I've been beating my head against this absolutely infuriating bug for the last 48 hours, so I thought I'd finally throw in the towel and try asking here before I throw my laptop out the window.
I'm trying to parse the response XML from a call I made to AWS SimpleDB. The response is coming back on the wire just fine; for examp...

Hello app engineers! I'm on an app engine project where I'd like to put in a link to a Javascript test runner that I'd like to only exist when running the development server. I've made some experiments on a local shell with configuration loaded using the technique found in NoseGAE versus live on the 'App Engine Console' [1] and it looks ...

I use Google App Engine. When I try to do a JPA query like this:
SELECT p FROM Participant p
WHERE p.party.id = :partyKey AND p.name=:participantName
I get the following error

I need to analyze app engine logs to know the bandwidth used. All requests show 0b for static files. How to change this behavior?
...
This request caused a new process to
be started for your application, and
thus caused your application code to
be loaded for the first time. This
request may thus take longer and use
more CPU than a typical request for
your application.
I've handled all the situations, also DeadlineExceededError too. But sometimes I see ...
Getting a weird error on java appengine code that used to work fine (nothing has changed but the data in the datastore).

I have a little app that runs fine on local dev appengine, but appengine itself is not processing my .jspx files.
The jspx files are in WEB-INF so they should not be excluded by appengine (as a static resource)
I am using Apache Tiles to define my views.
So the html produced looks like this:
<html

What is the difference between these 2 pieces of code?
query=Location.all(keys_only=True)
while query.count()>0:
db.delete(query.fetch(5))
# --
while True:
query=Location.all(keys_only=True)
if not query.count():
break
db.delete(query.fetch(5))
They both work.

I know that GAE does not support this yet, but is there any reason it can't be done? If they can add support, I'd assume they're working on that. Have they said anything about this publicly?

I am using the python app engine and finding that the log console on the local development server is terribly slow. Output to this window seems to show in chunks of about 5-15 lines every second. Is that typical? I find that it's so slow that it hinders my debugging time waiting for log data to appear.

I searched through multiple discussions here. Can someone just give me a quick and direct answer?
And if with JPA you can't do a batch update, what if I don't use transaction, and just use the following flow:

// make some data modification
em.persist(..)
