How to create an app that connects to facebook/twitter using Java and IBM webSphere? And what is IBM webSphere?

Question

I need to pull some data from Facebook/twitter by writing a code and by using Facebook graph API

Answer 1

IBM WebSphere is an enterprise application server, where you can deploy Java EE (enterprise edition) applications. If you really have to ask this question in the first place, then you are indeed very far from solving this problem. At the very least, you've got to research how the Twitter and Facebook APIs work and how to address them from a Java EE program.
