Hello,
I would like to build an web application where the entity relationship looks
like as follow:
User 1 - * Possibility * - 1 Country
1 - 1 Profile * - 1 Country
*initialization and persistence*
User.getPossibilities().add(Possibility);Possibility.setCountry(Country);
The request headers will not help.
You'll run into problems whenever you are doing an api call that
return with an unknown state and the method you are calling is not
idempotent (like sending mail, creating a contact etc.)
So in case of email you can add your app as bcc and use a mail-in
handler
Thanks, 3.6 as root was the problem.

So, if you are directly accessing the stream, it is still in memory
and not stored anywhere. I think you should try logging the stream you
receive. I think it is hitting a null ptr exception for some reason.

You definitely cannot share the data store between two applications as
of now.
But, you can definitely create another application a2 which contains a
webservice which can call a service from an application a1.

There is an issue in Eclipse with installing it as root, and then updating

I'd recommend that if you install Eclipse as root, switch to root when
updating your plugins.

You can do this now using the RemoteDatastore Java utility
http://code.google.com/p/remote-datastore/
For example, this code runs on your desktop and creates a single
entity in your live datastore:
// divert datastore operations to live application
RemoteDatastore.install();

Technically you actually can share data between applications using
RemoteDatastore - you can divert datastore operations to a different
application.
