IIQ - Quicklink File upload

We are trying to develop a quick link based file upload utility using a compass link as reference.

We have a custom workflow that gets triggered once we click on the quicklink. It redirects the user to the custom xhtml page we have developed. Post file upload in the xhtml, the .class is not being picked up.

Can anyone help with the custom xhtml file as we could not find any examples that would help with our scenario.
