Integration Google Calendar API with Apache OLTU

I'm trying to integrate the Google Calendar API using OLTU libraries.
When I try to execute the code request 1st step of OAuth2 dance, I receive an exception like the following:

19-Nov-2018 18:32:12.488 SEVERE [http-nio-8080-exec-5] org.apache.catalina.core.StandardWrapperValve.invoke Servlet.service() for servlet [Main Servlet] in context with path  threw exception

com.google.api.client.googleapis.json.GoogleJsonResponseException: 401 Unauthorized
{
"code" : 401,
"errors" : [ {
"domain" : "global",
"message" : "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
"reason" : "unauthorized"
} ],
"message" : "Request is missing required authentication credential. Expected OAuth 2 access token, login cookie or other valid authentication credential. See https://developers.google.com/identity/sign-in/web/devconsole-project.",
"status" : "UNAUTHENTICATED"
}

I'm developing a portlet and my code is:

OAuthClientRequest request = OAuthClientRequest.authorizationProvider(OAuthProviderType.GOOGLE)

                                .setClientId("<my clientID>")

                                .setRedirectURI("http://localhost:8080/c/portal/google_login?cmd=token")

                                .setResponseType(OAuth.OAUTH_CODE)

                                .setScope("https://www.googleapis.com/auth/calendar")

                                .buildQueryMessage();



        request.setHeader(OAuth.HeaderType.CONTENT_TYPE, "application/json");

        System.out.println("Location URI: "+request.getLocationUri());

Could someone give me any tips to solve this issue?

Many thanks.

Hi there, and welcome to Stack Overflow :) Have you followed the links in the error message, or otherwise looked up a "how to" on authenticating in Google's API's? The error is fairly clear: you need to use a token, cookie, or other credential to authorize your API request

I'm doing a token request as the first step to implement the OAuth dance. After as the second step I can use the token to ask the access token. from mail-archives.apache.org/mod_mbox/oltu-user/201503.mbox/…
