Hello,
I'm trying to simply read blobstore data without using the .serve()
method. It seems like I can use the .fetchData() method, but the
parameters needed are unclear to me and how I would generate them.
I just need to read all the bytes. For example if I store a plain/text
file in the blobsto
I was wondering if entity.getKey().getId() is going to stay the same
always, as I depend ID to bookmark entities.

.getKey().getId() returns an incremental number (starts from 1) on the
development server. However on the live server (when I deploy it to
Google) this number is quite large, for example 22007.
How come? Can I get incremental numbers starting from 1 on the live
server as it is on the development s

it should work out of the box... otherwise you're pretty much stuck

App Engine has been abstracting all their implementation details away
from the developer, which is great. I'm however a little curious in

These pages are only available on the development server, not when

I posted a question on StackOverflow about my data being stored with
weird chars, and it only happens live, which is very strange.

You could parse the appengine-web.xml file which contains the app name.

I think it's still a mystery so far. They seem to want to follow App
Engine's philosophy and free the developer from all the sys-admin
work, yet they provide implementation details (MySQL, Redis, and
MongoDB are listed on their site). This means that the developer will
still need to do some sys-adm
I have a Recipe entity that contains two images:
@PersistenceCapable(identityType = IdentityType.APPLICATION, detachable="true")
public class Recipe {
@PrimaryKey

private MyImage myImage; //
Whenever I query something like
public static MyUser getUserInfo(Key userKey) {
PersistenceManager pm = PMF.get().getPersistenceManager();
MyUser myUser, detached = null;
try {
myUser = pm.getObjectById(MyUser.class, userKey);

It's incredible I can't find any example online that involves editing
a child owned entity.

This is really weird. I cannot find anything on the internet that
could help me. It seems such a simple thing to be editing child
objects and I find it ridiculous that I can't find a solution.
please help

Well, I would think the Key has relationship information. The thing is
that I'm able to fetch the image for the recipe, so the relationship
is there somehow. It seems as if setImage() isn't enough for the
linkage to update to the latest image.

I don't see the actual Recipe being update with anything. I just see
the Image being added in the Image 'table'. But from the datastore
viewer there's no attribute in the Recipe 'table'. Hope that's clear.

It's the same when deployed to GAE. From the live datastore viewer I
don't see the children when viewing the Recipe entity itself. The
images get stored in another table called Image. Was I suppose to see
a reference to the image object directly in the Recipe entity?

Hello Simon,
even if I persist it doing
try {
r.setImage(newImage);
pm.makePersistent(newImage);
} finally {
pm.close();
}
I still get the same results. The interesting thing is that if I
delete the image entity from the datastore, the recipe
I have a Recipe. Each Recipe has an image. So my entity looks something like

@PrimaryKey

When I create the Recipe the first

I decided to go with datastore since I'll be storing simple thumbnail
images - nothing more than 100kb. I'm a bit afraid of the 30s limit
but I suppose it makes sense for Google. I work for a bioinformatics

of App Engine; hopefull
Ok. Thanks for the information. I'm still new at this cloud thing, and
it looks great.

Sorry, clicked on "send" before finishing my question.
Why does AppEngine set API limitations when I could just as easily use
a third-party library for manipulation and avoid this limitation?

Hello everybody!
I'm using Google AppEngine with their built in web server. My
development goes about in a simple way: I make changes to my .java
sources or .jsp and compile using ant and to see the changes I have to
restart the development server.
I'm wondering if there's a way I can avoid this
