When packager is deploying some project to jnlp package it contains some suspicious string:
<jfx:javafx-runtime version="2.2+" href="http://javadl.sun.com/webapps/download/GetFile/javafx-latest/windows-i586/javafx2.jnlp"/>

It links to some file under sun.com subdomain that is deprecated. Now this file can be downloaded from this place (from http://javadl.oracle.com/webapps/download/GetFile/javafx-latest/windows-i586/javafx2.jnlp is working too), but maybe it is wrong.

Maybe you shall see attached file with simple javafx project and run "ant deploy" to build and deploy project
