How to listen to a button click event within a iframe?

In my application,I have a JSP page where I need to embed a link inside a iframe which is generated from one other service. When the iframe is loaded, i need to perform some actions, where the control is not within my application. But when a button is clicked inside the iframe I need to call some java method within my application. How can I listen to a event within the iframe. Please help me out in this issue?

Call a java method or javascript method?

If the iframe is from another site, there can be no communications between the iframe and it's parent.

I'd set it up so that the remote site in the iframe can communicate back to the app via a web service.

Thanks for your reply.
I did not get a clear idea on what to set up. Could you please explain in detail.

You're not going t get a complete tutorial on web services in a forum post.
