Please give me some guidance with Struts2

I am practicing all the Form Tags and Generic Tags in struts2 .

I am scary seeing all them at once

There are a lot of them .

Can anybody guide me as how to proceed with them?? as where to start with .

Waiting for your precious advices.

I almost always start with trying to do something simple but functional, like a login page (uses a few form tags) or displaying a list of something (uses the iterator and optionally the property tag). Having some functionality in mind makes it more obvious where to start, IMO.
