Converting JavaObject to JavaScript and reading it from an Applet

Hi all! I'm a bit stuck with this concept that I've been working on and I'm looking for some sort of guide on this.
Essentially this is the problem:

Bean retrieves data from database and I need to store it as a hidden field on a webpage.
The user then must authenticate the data using an applet.
The resulting authenticated object is then sent to the database.

So i'm stuck at this paradigm:

Bean -> Html & Javascript -> Applet

I think I can figure out the upload issue later, thanks

The first thing to realize that you can only store text strings in hidden fields. So your first task would appear to be to convert this undescribed "bean" into a text string.

Yeah... I just figured that out and I'm working around it as I write. I'm also trying to use JSObject for reading the Javascript function return value right now. How do you get the value out of the enclosed type?

from what I gather the return type seems to be JSObject.
