AJAX and JSP are completely different technologies and are run on different systems and at different times.

JSP processors are executed when the page is generated, i.e. on the server side. AJAX functions are triggered in the browser by Javascript (hence AJAX) which is available after the page has been generated (using JSP) and delivered.

If the AJAX function triggers a JSP on the server side, the JSP or Servlet should read the needed parameter from the request first (the AJAX call would put it there), e.g. by accessing the implicit request object in an expression within the <jsp:include> tag.
