OAuthDataStore Guice Injection Problem

[pablo fernandez]

Hi,

I'm developing a shinding database backed site. I downloaded shindig for
Java recently, and tried to modify the code in order to make it work with a
different data store.

I started small, implementing just PersonService, but I always get this
exception:

com.google.inject.CreationException: Guice configuration errors:

1) Error at
org.apache.shindig.social.core.oauth.OAuthAuthenticationHandler.<init>(OAuthAuthenticationHandler.java:64):
 Error while injecting at
org.apache.shindig.social.core.oauth.AuthenticationHandlerProvider.<init>(AuthenticationHandlerProvider.java:36):
Binding to org.apache.shindig.social.opensocial.oauth.OAuthDataStore not
found. No bindings to that type were found.

My GuiceModule is this (note that OAuthDataStore is declared):

public class GuiceModule extends SocialApiGuiceModule {

    protected void configure(){
        super.configure();

 bind(String.class).annotatedWith(Names.named("shindig.canonical.json.db"))
     .toInstance("sampledata/canonicaldb.json");

bind(PersonService.class).to(org.self.opensocial.PesonServiceImpl.class);

        bind(OAuthDataStore.class).to(SampleOAuthDataStore.class);
    }

}

and here's the web.xml that loads all modules:

<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
         xmlns="http://java.sun.com/xml/ns/javaee";

Any ideas why this happens? If you need further info on my
configuration/code please ask!

Thanks in advance
