Error trying to access SmartCloud using OAuth

Question

I'm trying to use the Social Business Toolkit to access SmartCloud using OAuth, but I'm getting this error. Using SmartCloudBasicEndpoint everything works fine.

[4/4/14 12:01:56:560 CEST] 00000038 SystemOut     O Problem Occurred while fetching public communities: Problem occurred while fetching public communities

Here's what I've done so far:

• Create a new Servlet application.
• I'm using RuntimeFactoryStandalone.
• Added managed-beans.xml and sbt.properties (both from samples app) to /WEB-INF/.
• I'm running the application on WebSphere Application Server. (I also tried the same code in a Portlet on WebSphere Portal)
• Added the SmartCloud key, secret and appId to the properties file.

I'm using this code:

try {
    CommunityService svc = new CommunityService("smartcloud");
    CommunityList communities = svc.getPublicCommunities();

    System.out.println("Listing public communities , Total communities found : " + communities.getTotalResults());
} catch (Throwable e) {
    System.out.println("Problem Occurred while fetching public communities: " + e.getMessage());
    //e.printStackTrace();
}

I'm getting the same error if I manually use a SmartCloudOAuthEndpoint.

Am I forgetting something here?

Update:

My manual endpoint:

SmartCloudOAuthEndpoint endpoint = new SmartCloudOAuthEndpoint();
endpoint.setUrl("https://apps.na.collabserv.com");
endpoint.setConsumerKey("a91..----REMOVED FOR STACKOVERFLOW----..");
endpoint.setConsumerSecret("905..----REMOVED FOR STACKOVERFLOW----..");
endpoint.setRequestTokenURL("https://apps.na.collabserv.com/manage/oauth/getRequestToken");
endpoint.setAuthorizationURL("https://apps.na.collabserv.com/manage/oauth/authorizeToken");
endpoint.setAccessTokenURL("https://apps.na.collabserv.com/manage/oauth/getAccessToken");
endpoint.setAppId("RonnieTest");
endpoint.setApiVersion("apiVersion");
//endpoint.setHttpProxy("localhost:8888");
endpoint.setForceTrustSSLCertificate(true);
endpoint.setSignatureMethod("PLAINTEXT");
endpoint.setCredentialStore("SmartCloudStore");
endpoint.setAuthenticationService("communities/service/atom/communities/my");

I'm using this Internal App in SmartCloud:

Answer 1

I solved it. I wasn't passing ServletRequest and ServletResponse to my Context. Turns out that getCallbackUrl(Context context) in OAuthHandler is the first method that actually needs the request to build the callback URL.
