Implementing provider pattern?

I have seen some articles on provider patten. I have a little idea of开发者_如何学JAVA it and its benefit. I tried to see and do its implementation but got confused. Different authors have done it in different ways. I am very confused on how to do it. Some were using framework 1.1 but I am using 3.5 framework.

Please guide me or refer me some links on its easy and step by step implementation.

thanks a lot
