Rough idea:

1. Somwhere in script on your app html page define:
     function myFuncRequestCallback(answerFromServer) { ... }
     This  procedure will receive answer from the server.

2. In html define invisible <IFRAME id=myiframe>
3. To call remote procedure on the server (jsp page) do following:
    myiframe.open(...jsp?your call parameters);

Document produced by this JSP should have <SCRIPT> block with something
like:

<SCRIPT>
var answer = {  answerField1: "hello",  answerField2: "world"}
window.parent.myFuncRequestCallback( answer );
</SCRIPT>

Minus of this approach - asynchronous call;
Plus - you don't need to parse response it will be delivered as ready to use
JS object (map in this case)
