We are happy to help people learn but we will not do your work for you. We're all just volunteers helping out in our free time, not unpaid consultants.
Our
Struts FAQ has links to some good learning resources. The
Struts 2 Getting Started Guide is another good place to start. I recommend completing a couple of tutorials so you get the basics of how the framework functions before trying something like AJAX.
Once you've got the basics, feel free to come back here with whatever questions you have. And don't forget,
the better question you ask, the more help we can be.
