Does anyone have tried to implement an app in GAE having both java and
python?
I have an existing app and my front end is in java. Now I want to use
the existing datastore to be interfaced by python. My problem is i
don't know how to define the relationships and model that would be
equivalent
The objects have been detached.
Ok. So the objects *have* been read from the datastore, since to
detach them you obviously have to retrieve them first ... then detach
them. And the exception is presumably coming from GWT, but then I
don't see your stack trace so have no way more than guessing.
Hi!
It is pretty common usecase for public sites - admin uploads some
static html+css+images via and it is served from some servlet in
application in structured way.
Of course in GAE it is imposible directly, but could be simulated.
We could store hierarchical info in some entity structure
It depends why you're making the tweaks - if you are just testing the
CSS to make sure a certain tweak has the desired affect, then you
could use something like Firebug to change the CSS on a particular
page until it's correct. However, if you want that change to persist
across multiple pages

Hello,
I was developing a web application and I needed to add chart

Hey all,
I have a signed java applet (voice recorder) that I've been using on
GAE/J for the past few months. I use maven-jar-signer to do the
signing. Everything had been working great but I upgraded to SDK
1.3.1 and saw that precompilation was causing the following error:
failed wicket.google
Are you serving the applet out of WEB-INF/lib somehow? We should only be
processing jars in that directory.
If you're serving this files to clients you should be able to either place
it outside of WEB-INF and let it be served as any other static file, or
store it somewhere other than WEB-INF/lib

Hi,
Can we generate excel sheets using the google app engine? I have seen
some posts and support for Python but nothing on the Java side.
Is it possible to generate an Excel report using the google app
engine? Or shud we rely on the streams to generate a workbook.
Thanks.

That would be great if you could post your workaround!

I've been scratching my head over this one for a while...
I have a parent object that participates in an owned one-to-many
relationship with a child object. After the parent object is created,
it is retrieved with its collection of children in the selected fetch
group, and then detached. Then,
MODEL OBJECTS:
@PersistenceCapable(detachable = true)
@FetchGroup(name = children, members = { @Persistent(name =
_Children) })
public class Parent {
@PrimaryKey
@Persistent(valueStrategy = IdGeneratorStrategy.IDENTITY)
private Key _ID;

hello
how can I get URIINFO object in Google app engine from jersey API.we
use this class object by context inject annotation in JEE container but app
engine it produces exception.
*InitialContext* is a restricted class. Please see the Google *App

guide for more details
I am trying to remove an object from the datastore without and I want
to know if my approach can be made to work with transactions.
I have a collection of entities that all participate in owned
relationships. However, one entity has an unowned collection of keys
that refer to another entity.
has anyone got this running? Even i want my application to generate a
report in the form of an excel. Can this be done on the GAE platform?
I dont see any threads in Java. However looks like python supports it.

Not sure I follow. We plan on deploying it only once, on AppEngine.
We'd like to use a single instance of the app but differentiate one
customer's implementation from another's via the URL. It's similar to
twitter where each user is differentiated like twitter.com/user1,

I think you have to use two queries and merge the results afterwards
in your code. As you said, datastore does not allow you to use
inequality filters and logical or operators on more than one
property. I guess from a performance perspective this doesn't make
much difference. Appengine would have

Ah, I see. I misunderstood your original question: I thought you
wanted to deploy a single GWT frontend and have it talk to multiple
App Engine backends.

I'm not exactly sure what you mean when you say GWT applications go to
a single URL. Have you asked on the Google Web Toolkit groups
(https://groups.google.com/group/google-web-toolkit?pli=1)? This is a
generic servlet question, so any answer you are given should also
apply to App Engine.

If you're using GWT, you can at least skip the GWT compile on deploy
by using appcfg update instead of the deploy button in Eclipse.

Hello Ikai L thanks for your reply.
You just have to persist the Person first, or create a Person, attach

entities, then call pm.makePersistent() on the Person.
but this is problem. Telephone must not belong to Person.

Hi Damob,
They work perfectly together because your data models are *pure* POJOs
with no dependencies on the datastore at all.
In contrast, in JDO, JPA, Objectify and SimpleDS your data models
usually use low-level Keys and possibly other types. This means that
you either need to make
Yes, a lot actually. I was asking myself that question since I introduced in
my POJO's some TWIG annotation and didn't know if those information are
compatible with GWT-RPC Mecanism.
I'll give a deeper look into twig tomorow.
Thanks

Yeah the annotations are fine. The GWT compiler does not include them
in the compiled JS code.
