title: Post to Facebook Page wall using RestFB api
body: <p>I am trying to post on the wall of a facebook page. I am able to post on the user wall using App Access token.</p>
  
  <p>I got the App Access Token through extending the DefaultFacebookClient</p>
  
  <pre><code>public class ConnectionService extends DefaultFacebookClient{
  
  public ConnectionService(String appId, String appSecret) {
      AccessToken accessToken = this.obtainAppAccessToken(appId, appSecret);
      this.accessToken = accessToken.getAccessToken();
  }
  }
  </code></pre>
  
  <p>With this I  am able to post to user wall using the appID and appSecret. But when I tried to post to Page Wall
   i get error of " The user hasn't authorized the application to perform this action"</p>
  
  <p>Anyone can advice?</p>
