Just let JSP print it as if it is a JS variable. Assuming that you’ve variable ${foo} in JSP:

<script>var foo = '${foo}';</script>

This will end up in webbrowser as

<script>var foo = 'somevalue';</script>

Keep in mind: JSP runs at webserver and produces HTML. JS is part of HTML and runs at webbrowser.
