I am looking for a simple Amazon web service library. I plan to use it
in a struts application.

Basically, I want a library that once I provide with an ISBN for a
book, it will return current book price, image, reader comments
(optional), and, of course, URL to this book. I want to wrap all those
in a javabean and use it in a jsp page.

No other fancy features required for this simple library.

Any recommendation?

Thanks
