How do java call javascript?

Hi all,
I would like to know how can a java application(not applet) calls a function from a jsp and vice versa. All the example I have found are all relating to java applets.
Thanks.

First of all, a jsp is usually a Java ServerPage not JavaScript. Different things.
JavaScript only runs inside a broswer and uses HTML to interface with the user. There is no java involved in javascript. The browser is reading the javascript and doing the logic. No browser - no javascript functionality.
I don't see how this could be done.

Cindy,
you're right; though I've heard about some Javasript extension for server-side(not browser related) scripting; not sure why Java not enough though.

there any options for JavaScript.
