Hi Ikai,
I noticed the "overview" link for the prospective search points to the
Python version of the page, rather than the Java version.
So please just change "python" to "java" in the URL :-)
Fortunately, the "java" page already exists.
Congrats on the release, I was impatient to look at that p
Hi all,
I need to collect some statistics on my entities in the datastore.
As an example, I need to know how many objects of a kind I have, how
many objects with some properties setted to particular values, etc.
In usual relational DBMS I may use
SELECT COUNT(*) ... WHERE property=
or
SELECT MAX(

Write a MapReduce mapper to count everything and consolidate back to

My only two comments are:
- MemCache can contain null values - it wouldn't be the cause of your
issue but it's worth checking for null, rather than assuming that the
returned value has a length.
- Your data will never stay in MemCache for 30 days - how often are your
calls betwe

Since a few days I get SocketTimeoutException when trying to communicate
between two different apps running on app engine.
App A calls B, B calls back A and this causes the timeout.
I've increased the URLFetch timeout to the max but still see this error. It
is reproducible.
I've turned threadsafe
Hello
I am using Java for Google App Engine on my site
http://game-lie.appspot.com/ It is based on PHP.
But while connecting to any database on any server, I can't establish the
connection.
Please take a look or give me access to connect my application to any other
server.

Hi,
You can't connect GAE applications to external databases directly. The only
external connections which are allowed are connections over the HTTP
protocol.
Cheers,

Sorry, I should also have added that GAE doesn't currently support PHP
either!

I took suggestions from Nicole and it seems to be working now.. Although I'm
still uneasy about it. How does contains(key) work? If I store a non-null
value into the Memcache, why would get(key) ever return null?
What's wrong with the existing code that I posted that Memcache.hasById(id)
always
Hi
Anyone has idea on how to make changes to appengine datastore from a java
client running on your local desktop? My test app in the original post
connects successfully to my remote app with "Remote API". But the standard
JDO persistence API calls fail. Am I missing any steps? The same code w

Hi,

Dear group,
I would like to know whether there is way to detect the event of
instantiating another instance of app.
I need to detect it to trigger clearing local cache what I like to put as a
layer before memcache.
Because it's the local cache, I like to simply clear it for sychronization

Hi,
You could try (didn't do it myself) the load-on-startup param with a
value > 0 in the definition of a given servlet within
web.xml
This starts the servlet when the application is deployed in starting
container.
That should allow you to do what you want

Hi,
I'd hope that the value is never null, it was just an observation. How long
is there between a *putById *and a *hasById*?
