How to combine JavaScript within JSP statements

Question

I have trouble figuring out how you can get a value from your JavaScript and insert it into a JSP Object.
I have a JavaScript function like this:
function setCookie(user) {
<%
Cookie cookie[] = request.getCookies();
for (int q = 0; i < cookie.length; i++)
     if (cookie[q].getName().equals("username")) {
     cookie[q].setValue(user);
     break;
%>
I wish to add the user variable of the JavaScript into the cookie[q]'s value. Is this possible? If so could anyone please help me in telling how to do this or maybe an alternative method.
Thank You

A call to JavaScript goes to the browser on client. A JSP request goes to the JSP container on the server. Therefore to
get a value from your JavaScript and insert it into a JSP Object.will require a request to the server and response back. You could use a form to send the "user" value to the server and the JSP could send response to the browser to set the cookie.
or maybe an alternative methodWhy don't you use a pure JavaScript solution. Your JavaScript function could set the cookie directly. JavaScript can manipulate cookies by using the "cookie" property of the Document object.
