using dyuproject on gae java

[Don]

Hi,

I am trying to use openid/hybrid in app engine, but so far, no luck.

No success with openid4java (because it creates socket etc), and no
luck with dyuproject either.

How do it deploy dyuproject into my java appengine?
I just could not understand the different structure of the code in
http://dyuproject.googlecode.com/files/dyuproject.appspot.com-source-2009-10-08.zip
It is just so different than the default new google web application.

Many thanks..

I have been struggling the whole week...

What web framework are you using?
If you look at the sample webapp, it interacts with the servlet api directly ... no high level abstraction.
The RequestContext basically wraps HttpServletRequest and HttpServletResponse.

Can you give a link about this new google web application you mentioned?
As far as I know, on appengine any servlet-based war/webapp can be deployed.
And java webapps are all servlet-based.

Cheers

Hi,

Also I put the webdefault.xml under WEB-INF directory along with
web.xml
I assume it's safe?

Many thanks

Hi,

my url: http://3.latest.dontestjava.appspot.com/
I copied and pasted your dyuproject 1.1.6 files into a new project
using war directory.

I can access http://localhost:8080/hybrid/ in localhost, but not on
app engine..in localhost i got redirected to google to signin, altough
then I got 401 Unauthorized (presumably because it's in localhost?)

i got this exception when trying to access /hybrid (http://
3.latest.dontestjava.appspot.com/hybrid) on app engine..i dread to
think that this is another config error :(
please help...

Hi,
It's all good now..just a matter of file locations...

Thanks

Hi again,

Now that the hybrid+oauth are working, is there a tutorial that guides
me of how to use the OauthGoogleService and the other services?

Basically i want to use hybrid openid+oauth as authentication for my
website,
and somehow i have to save the openid, accesstoken, and email address
on gae datastore.
It's not really clear from reading the code of how to do this..please
provide guidance..

many thanks

Since you are using the hybrid, you only need to persist the OpenIdUser.
All the other tokens, you can set as attributes of OpenIdUser.
The id of the entity could be:
1. openid.identity -    guaranteed to be unique (this is generated by your openid provider)

2. openid.claimedId - guaranteed to be unique. If the user uses his own site (or blog site) as the claimedId
                               and delegates to a 3rd party openid provider with a local id, that would be the
                               claimedId used. 
                               If the delegate doesn't specifiy a local id, the value of claimedId == openid.identity.
                               If he is not using his own site (or blog site), the value of claimedId == openid.identity.
                              
Advantages of using #2:
- if the user opts to change his delegated openid provider, he will not need to re-register to your site.
If using #1, he will have to re-register. 
Basically #2 is the most flexible.

The value of the entity (
1.  Serialize it with JSON. 
     Entity.setProperty("openid_user", StandardJSON.toJSON(OpenIdUser));
2.  Serialize it with default java serialization.
     Entity.setProperty("openid_user", new Blob(serialized_bytes));
    
     Where the serialized_bytes is generated from:
       ByteArrayOutputStream baos = new ByteArrayOutputStream();
       ObjectOutputStream out = new ObjectOutputStream(baos);
       out.writeObject(OpenIdUser);
       byte[] serialized_bytes = baos.toByteArray();

I suggest you use the low level api of the datastore for this.

In the very near future, I will be removing the dependency on jetty-util.
For that release, the default serialization will be protobuf. (which can transparently be transformed to JSON as well).

Hope that helps
