Eclipse RCP中的Ajax

Is there a way to use any AJAX like components in an Eclipse RCP application though without migrating to a RAP platform? If migration is the only way, is there any tool/wizard that will help the application to be converted from RCP to RAP platform?

Any pointers will be of great help.

So you want a thick client or thin client (web browser)? or you want to migrate UI components from thin client to thick client (RCP)? Please clarify.
