Javascript code on the client cannot access Java objects that were created
in the JSP page on the server!
The link that I gave you shows you how to create javascript code using jsp,
BUT the jsp code itself is only executed at the server and the javascript
code that is dynamically built by the jsp code is only executed on the
client, so the two technologies cannot share objects (I think the web
article clearly explains this). I you want the client to access Java
objects, I think you'll have to use applets instead somehow.
So, if you want the browser to send back data to the jsp on the server,
here's how Hans says you need to do it in the article:
"To only way to pass data from the browser to a JSP page is to pass the
data as HTTP request parameters. If the data is generated by JavaScript
code in the browser, the JavaScript code can set hidden form fields or
the query string of an <a href> element, and this way get the data sent
to the page with the HTTP request. To the JSP page, it doesn't matter how
the parameter value was assigned; it uses the parameter value exactly
the same way as it uses a parameter value passed as a regular form
field value or a hardcoded query string."
