Hi Iam using the exact code from this Tutorial
This is the code of my two servlets
LoginServlet.java
try {
TwitterFactory factory = new TwitterFactory();
Twitter twitter = factory.getInstance();
twitter.setOAuthConsumer(Consumer_Key,Consumer_Secret);
RequestToken requestToken = twitter.getOAuthRequestToken();
String token = requestToken.getToken();
String tokenSecret = requestToken.getTokenSecret();
session.setAttribute(“token”, token);
session.setAttribute(“tokenSecret”, tokenSecret);
String authUrl = requestToken.getAuthorizationURL();
request.setAttribute("authUrl", authUrl);
RequestDispatcher rd = request.getRequestDispatcher("twitter.jsp");
rd.forward(request, response);
}catch(Exception e){
out.println(e.getMessage());
}
and
HomeServlet.java (as callback URL)
TwitterFactory factory = new TwitterFactory();
Twitter twitter = factory.getInstance();
twitter.setOAuthConsumer(Consumer_Key, Consumer_Secret);
AccessToken accessToken;
try {
accessToken = twitter.getOAuthAccessToken((String) session.getAttribute("token"), (String) session.getAttribute("tokenSecret"));
twitter.setOAuthAccessToken(accessToken);
User user = twitter.verifyCredentials();
out.println(user.getId());
out.println(user.getMiniProfileImageURL());
} catch (TwitterException ex) {
out.println("************************************");
out.println(ex.getMessage());
out.println(ex.getErrorMessage());
out.println("************************************");
//Logger.getLogger(TwitterLogin.class.getName()).log(Level.SEVERE, null, ex);
}
Here Iam getting the response from callback url is
“401:Authentication credentials (https://dev.twitter.com/docs/auth) were missing or incorrect. Ensure that you have set valid conumer key/secret, access token/secret, and the system clock in in sync.
The screen name / password combination seems to be invalid.”
Please help how to solve this. I had already set the Application Type as Read, Write and Access direct messages.
