I am writing a posting engine to run on Glassfish which posts to Twitter from a database queue.
I am using the Scribe Java API for doing this. I am having an issue with performing a signRequest from the OAuthService. I have a valid access token and have the tweet to send out - Below is my code for where the error is occuring.
String urlTweet = "https://api.twitter.com/1.1/statuses/update.json?status=Tweet To Post";
OAuthRequest tmpRequest = new OAuthRequest(Verb.POST, urlTweet);
oAuthService.signRequest(accessToken, tmpRequest); // THIS LINE THERE IS AN ERROR
response = tmpRequest.send();
However I am getting an error on the line shown above. Here is the stack trace for what I am getting - parts have been redacted for anonymity purposes.
