I have to do Login Authentication to post the tweets. I got the Jtwitter.jar and SignPost.jar file from this link. As far as i searched, the xAuth Authendication is more efficient. But i did not get any simple tutorial or piece of code for Login Authendication yet. I found this Article and used this code. thats get NullPointerException.
I created the customer key and Secret key also used the code where got the jar site. That gets Verification Error.
Please Share some idea or steps to follow to verify the username and password of the user?
Edit:
I want to post to from the user's account. what do you prefer to use the Api whether Jtwitter or Oauth? and Tell me How-to or Related Articles ?
