Using Google API with spring-security-oauth2.0

I've searched here a bit but could not find an answer to my issue. I implement oAuth client with spring-sec-oAuth 2.0 (1.0.0.RC2a). After properly setting the beans.xml, I happily get a valid token and all looks good. Then, I want to use Calendar APIs - I'm not sure how do I make the call to get the Calendar object. My (relevant) settings: (spring-servlet.xml) ``` <!--apply the oauth client context--> <oauth:client id="oauth2ClientFilter" /> <oauth:resource id="google" type="authorization_code" client-id="<my client id>" client-secret="<my client secret>" access-token-uri="https://accounts.google.com/o/oauth2/token" user-authorization-uri="https://accounts.google.com/o/oauth2/auth" scope="https://www.googleapis.com/auth/calendar" client-authentication-scheme="form" pre-established-redirect-uri="https://ohad.sealdoc.com/oauth2-client/hello" /> <bean id="googleClientService" class="com...GoogleClientServiceImpl"> <property name="butkeDemoRestTemplate"> <oauth:rest-template resource="google" /> </property> ``` and the implementation class: ``` public class GoogleClientServiceImpl implements DemoService { private RestOperations butkeDemoRestTemplate; @Override public String getTrustedMessage() { String dataUri = "https://www.googleapis.com/calendar/v3/users/me/calendarList?minAccessRole=writer"; Calendar service = butkeDemoRestTemplate.getForObject(dataUri, Calendar.class); return "demo"; } } ``` Doing so ends up with: Request processing failed; nested exception is error="invalid_request", error_description="{errors=[{domain=usageLimits, reason=accessNotConfigured, message=Access Not Configured}], code=403, message=Access Not Configured}" Definitely, I'm doing something wrong in my "getTrustedMessage()", so I'm hear to consult the experts... I DO want to use OAuth2RestTemplate, but how do I know the URI I should use? After searching (Google), I found only examples of Google code, and they use Google oAuth (which I do not want to use - I'd rather use Spring implementation for my client) any ideas?
