JSP code has nothing much to do with jQuery. JSP executes on the server; jQuery on the client. All that matters is what is sent to the browser.

So rather than look at the server-side code, look at what is sent to the browser. Is it correct? Is it valid? What's different?

By the way, Java code in a JSP is a very poor and obsolete practice from 12 years ago. You should no longer be putting Java code in JSPs.
