As far as I know you cannot directly communicate from Javascript to JSP. There is a fundamental problem here and that is that a JSP page is transduced into a servlet and outputs HTML/XHTML that can contain Javascript or link to a Javascript file. Javascript is utilized by the browser, so there is no JSP per se to talk to, just HTML/XHTML to act on.
However, you could have them communicate indirectly. You could have Javascript do a submit a form with paramters and direct this to a JSP and the JSP can parse out the paramaters. If you direct the submit to the same JSP, you are in a sense passing information to the JSP.
Another mechanism that is available is that Javascript has the capability to communicate with an Applet. The Applet can open up a socket or whatever with the server it as served from and communicate this way to the server.
In addition, Javascript can write to a cookie and information can be passed to JSPs this way.
