LinkedIn Oauth2 throws exception using Scribejava - oauth-2.0

Question

This is the code from the tutorial Getting Started and I'm only trying it, nothing else is running.
public class Launch {
private static final String url =
"http://api.linkedin.com/v1/people/~/connections:(id,first-name,last-name,email-address,picture-url)";
private static final String url2 =
"http://api.linkedin.com/v1/people/~/connections:(id,first-name,last-name)";
public Launch() {
OAuthService service = new ServiceBuilder()
.provider(LinkedInApi.class)
.apiKey("xxxx")
.apiSecret("xxxx")
.build();
Token requestToken = service.getRequestToken();
String authUrl = service.getAuthorizationUrl(requestToken);
Verifier v = new Verifier("verifier you got from the user");
Token accessToken = service.getAccessToken(requestToken, v); // the requestToken you had from step 2
OAuthRequest request = new OAuthRequest(Verb.GET, url2);
service.signRequest(accessToken, request); // the access token from step 4
Response response = request.send();
System.out.println(response.getBody());
}
In my controller I have:
#View
public Response.Content index(){
Launch launch = new Launch();
return index.ok();}
and when I try to launch it, it gives me this error:
org.scribe.exceptions.OAuthException: Response body is incorrect. Can't extract token and secret from this: 'oauth_problem=permission_unknown'

Answer 1

Found the solution: changed the code to add Scanner in = new Scanner(System.in); after the ServiceBuilder declaration to use it in Verifier verifier = new Verifier(in.nextLine());
And also, put manually the url found in the terminal which is the result of System.out.println(service.getAuthorizationUrl(requestToken));
It's a temporary url, but the only way this works till now.
