Do you mean having Java code on the server and needing to sign the document on the client side? Such task requires having client-side mechanisms (usually a Java applet or ActiveX control or some standalone application) which will do the actual signing job.

Our SecureBlackbox library has a distributed cryptography add-on which lets you accomplish the task easily. You will find detailed description of the add-on on our site or in this SO answer.

If you need to sign the data in client-side Java code (i.e. the USB device is local to the code), then you can use PDFBlackbox package of our SecureBlackbox product - it supports operations with USB tokens and cryptocards.

I've written a white paper about digital signing and PDF. It also explains what such an USB token is about. You can download this document for free from this URL: http://itextpdf.com/book/digitalsignatures
