OAuth_verifier is absent

[SwapnaThorve]

I am using scribe-java for implementing Google Authentication. I could successfully implement it for Facebook. Following is the code. I am facing issues in retrieving the oauth_verifier.

System.out.println(">> Create OAuth Service Object...");
gsService = new ServiceBuilder()
.provider(GoogleApi.class)
.apiKey(ParameterDetails.GP_API_KEY) // client Id
.apiSecret(ParameterDetails.GP_API_SECRET) // client secret
.callback("http://localhost:8888/ScribeOauth/ResponsePage.jsp")
.scope("https://docs.google.com/feeds/")
.build();

// Get request token
System.out.println(">>> Getting request token...");
Token gReqToken = gsService.getRequestToken();
System.out.println("\tRequest Token: "+gReqToken);

// Authorization URL
System.out.println(">>> Authorization url...");
String gsAuthUrl = gsService.getAuthorizationUrl(gReqToken);
System.out.println("\tURL: "+gsAuthUrl);

// Place the verifier
System.out.println(">>> Extracting verifier");
System.out.println(request.getParameter("oauth_token"));
System.out.println(request.getParameter("oauth_verifier"));
System.out.println(request.getAuthType()+"\n"+request.getQueryString()+"\n"+request.getPathInfo());

Verifier gsv = new Verifier(request.getParameter("oauth_verifier"));
System.out.println("\tVerifier: "+gsv);

// Get access token
System.out.println(">>> Getting access token...");
Token gAccToken = gsService.getAccessToken(gReqToken, gsv);
System.out.println("\tAccess Token: "+gAccToken.getToken());

------ Following is output ------

I cant proceed ahead because the oauth_verifier is not there in the Url.
I tried assigning null value, or giving a particular sequence. I also tried using get Query parameter methods on the URI, still it gives null. Also I thought I l redirect the user to the Auth url so that I get that parameter, but it still didnt work. (I had redirected the user to the AuthUrl while implementing for facebook). Also are the parameters passed while building the serviceBuilder object correct?
I am running the project as a Dynamic Web Project on a localhost.
Can anyone please help? I have no idea how do I proceed.

Seems, it's not actual. Google Api is 2.0 now and there is no oauth_verifier anymore ;-)
