How do I communicate Javascript data in JSF?

Question

I am developing an application that performs digital signature. In it, I upload a file PDF that has the address stored in a variable JavaScript. In the background, there is an application in JSF, which has the nature to sign my file PDF.

What I need is that the JSF get the signature file through my application JavaScript.

Would anyone know how to direct this data from JavaScript to the JSF?

Someone has already developed digital signature applications, and could explain me better how to get files for signing other applications?

You have to pass this "address" to your JSF. You can pass it by including it in some form field that will be submitted or you can do it directly with javascript using the JSF js API: http://www.javabeat.net/jsf-2-ajax-javascript-library/
