JavaScript and JSP don't run on the same processor.
I mean, JavaScript runs on client side, while JSP is server side scripting.

The if statements of JavaScript can't lay a condition for JSP.
Have a look at view source for your page, you may come to know why is is not working.

Absolutely! To solve this, either cause a page reload onchange which sets the session variable or use Ajax.
