Java variables inside Javascript

Question

I have a variable declared outside my javascript function which gets its value from session.

   String elementID = session.getAttribute("elementID");
   <SCRIPT>
        var a = "123"
        elementID = a;
   </SCRIPT>

Will this work out? i need to assign the value "123" to the string variable elementID.

This is not simply possible, since Java runs server-side and JavaScript client-side.

You can't assume that the JavaScript (that won't be evaluated until it's on the client) knowns anything about Java. It doesn't.
