  1. POOAuth: HTTP 401 Status when trying to get access token to LinkedIn
    text
    copied!<p>Using <a href="http://code.google.com/p/linkedin-j/" rel="nofollow">linkedin-j</a>, I have the following code in one part of my application</p> <pre><code>LinkedInOAuthService service = LinkedInOAuthServiceFactory.getInstance() .createLinkedInOAuthService(consumerKey, consumerSecret); LinkedInRequestToken requestToken = service.getOAuthRequestToken(linkedinCallbackURL); String authUrl = requestToken.getAuthorizationUrl(); </code></pre> <p>I redirect to the page pointed by <code>authUrl</code> and get to the correct LinkedIn page where I authorize my application. Then, the code which generates the page pointed by <code>linkedinCallbackURL</code> will execute this:</p> <pre><code>String verifier = request.getParameter("oauth_verifier"); LinkedInOAuthService oauthService = LinkedInOAuthServiceFactory.getInstance() .createLinkedInOAuthService(consumerKey, consumerSecret); LinkedInRequestToken requestToken = oauthService.getOAuthRequestToken(); LinkedInAccessToken accessToken = oauthService .getOAuthAccessToken(requestToken, verifier); </code></pre> <p>Unfortunately, I get this error:</p> <blockquote> <p>com.google.code.linkedinapi.client.oauth.LinkedInOAuthServiceException: oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Server returned HTTP response code: 401 for URL: <a href="https://api.linkedin.com/uas/oauth/accessToken" rel="nofollow">https://api.linkedin.com/uas/oauth/accessToken</a></p> <p>Caused by: oauth.signpost.exception.OAuthCommunicationException: Communication with the service provider failed: Server returned HTTP response code: 401 for URL: <a href="https://api.linkedin.com/uas/oauth/accessToken" rel="nofollow">https://api.linkedin.com/uas/oauth/accessToken</a></p> </blockquote> <p>What can be wrong?</p>
