JSF / ManagedBean equivalent for JnlpDownloadServlet
===

http://docs.oracle.com/javase/1.4.2/docs/guide/jws/downloadservletguide.html

explains how the servlet can be used add data at runtime using $$ syntax

example
    <jnlp codebase="$$codebase">


Any ideas how something similar could be achieved where also managedBean data could be included using #{managedBean.attribute}.
