I used java-cloudfiles-1.0.jar (of rackspace) , I need to know what is the new version of this jar and from where i can download it. can you please elaborate and send the link ?
The latest version of java-cloudfiles is 1.10.0. You can get it by downloading it from the Rackerlabs GitHub page and building it with ant.
However, you should be aware that java-cloudfiles has been deprecated in favor of jclouds. More resources are also available on the Rackspace SDKs page. If you're already upgrading, I'd recommend changing to the newer SDK instead!
