Hi Owen,
What I do is to touch the fields I want which are not in my default
fetch group before closing the persistence manager:
@PersistenceCapable(identityType = IdentityType.APPLICATION,
detachable = "true")
public class Thing implements Serializable
{
private static final long serialVersio
The best thing I have come across is:

I hope that is some help I am going down a similar path to yourself it
would seem.

The GAE datastore doesn't support fetch groups for entity properties.
You get back all the properties whenever you load an entity.

Hello group,
How do I write a custom fetch group for my GAE project?
I have a class A that contains two fields, B and C. Sometimes I only
want to retrieve A + B, sometimes A + B + C. I have a feeling a custom

Hi,
I'm using the 1.3.4 version of app engine. I noticed that now we have:
com.google.appengine.repackaged.org.json.*
available. I can use the json classes and compilation is fine, but at
runtime loading of the json classes fails, I think:

Well, this is only my opinion, but I wouldn't go this way. I think a simple
Ant file with Ivy perhaps will be a better approach than using Maven. It
does not feel (to me) that a GAE is really a "maven app", it actually look a
lot more like an Ant application... (but again, only my opinion here)

I created an app engine project (without GWT). All looks good: Folders

Now I have m2eclipse and enabled the dependency resolution. I don't

Technically several applications use the same Bigtable:

That being said, you are probably asking if it is possible to use the same
datastore for multiple applications: the answer is no. There are several
threads about how workaround
There are a few threads in the groups about this. Here's an older one. To

What aspect of Memcache is too slow? Have you run AppStats yet?
The overhead of Memcache is low enough for many of the top sites on the
internet to use. Some sites are listed on the main page here:

As you move closer and closer to local memory, the volatility of your cache

Hello,
I am new to App Engine. I just tried sample applications of App Engine
services.
I dont want to deploy my application on Google App Engine but I want
to use Blobstore as Image Storage.
Since Blobstore is payable, Is it possible to use blobstore service/
API outside the Google App Engine?

No it is not open source. It was mentioned at Google IO that more

Thanks. It is a nice improvement compared to 1.3.2 where we had to
deploy (and re-compile) 2 to 6 times.
With 1.3.4, it does not report an error after trying several times.
But it is still taking a lot of time, as the final stage (actual
deploy) is taking a while:
Deploying new version.
Will check

Hello,
I wonder if there is a framework (such as Objectify) also for
memcache. As memcache is not on the local machine it is rather slow,
especially for reoccurring requests. So on Google I/O they suggested
to build your own in-memory layer around that. I know that is an easy
task, still I wonder
Hello,
I agree with what was said before and I think essentially all these
frameworks are somehow similar. You should pick what fits best in your
application.
Personally I also went for Objectify because it is so well documented.
Actually by using it I started to understand the tricky parts of th
