Hi Jonas,
Yes, moving to Objectify is definitely a good move: especially since
the GAE google team pushes toward 3rd party package rather than
datanucleus impl of JDO/JPA currently used by GAE.
But, it doesn't sometimes prevent the need of DTO: if, for example (my
own cas), you want all your back
Ok guys, even if the gql query is running I'm still not able to port
this logic into my java class.
Maybe someone could have a look at my code and correct/refer to my

StringValueConversionException {

Hi Jonas,
I am a fan of Objectify: i abandonned JDO for Objectify.
But, I had the need for DTOs anyway: what you state about GWT & Ofy is
true, but if your mixed (front-end + back-end) objects needs to
inherit from a hierarchy in the back-end to have generic functions
then you are in trouble beca
hi,
take a look at the persistance framework "Objectify"
http://code.google.com/p/objectify-appengine/
Objectify entities can be used in GWT without the need for Data
Transfer Objects.

Hi GeneralSlaine,
I use the same approach to preserve GWT from back-end specificities.
To answer your question, I reduced my helper code to a minimum by
using java reflection to copy front-end version to back-end version
and vice versa. The code is a bit complex but it's written once for
all clas
You're almost always going to want to use String. The specific property
types have very weak validation (basically not null) but have been known to
cause issues. They were introduced to make serialization to XML easier, but
very few developers actually care about this feature.

So far, I have not managed.

You can try touching (i.e. re-saving) your appengine-web.xml file. That

I'd really appreciate some help with an issue I'm having. The crux of the

Hi,
I saw that everybody had some problems with XStream and Gae due to the
restriction of google. Is there someone who has the xstream.jar that can run
correctly on the server of google. I mean the .jar builded with the patch
located at this url :http://jira.codehaus.org/browse/XSTR-566.

Hi Vishnupradeep,
Absolutely! In my gaelyk app, I place the static content (images,
javascript and css) in the /war/ directory. So, you'd
have /project/war/images/img.png or /project/war/css/style.css
As for referencing them, you would just use the absolute path of:
/css/style.css or /images/img.
I think HTML development in appengine is same as what you do in the other
type of site either local or own server.
Therefore, Sure, CSS is possible.
You may found CSS tutorial from: http://www.w3schools.com/css/default.asp

Hi,
Yes, you can.
Example is here

Then you should read

Hi,
To my knowledge it is impossible based on infos provided by GAE: the

upload process.
So, no hope from back-end perspective but maybe possible from a front-
end perpective it the client can detect and feed the loading bar with

Is anyone else seeing this today?

What are the advantage of data type like PhoneNumber o Email (
