Answer 1

I was also facing the same problem as Twitter no more supports REST 1.0 from June 11'13. But I fixed the problem by replacing with the latest twitter4j jar file.If you are using twitter4j jar for your application to authenticate with twitter means it will definitely work for you.

1.Download the latest twitter4j from here

2.Replace it with the older one and you are done.

EDIT

Initially after replacing the twitter4j jar, it may show error in package importing. if so then replace

import twitter4j.http.AccessToken;

with

import twitter4j.auth.AccessToken;
