Subject Re: PDF File content ist not visible

If you're working with JAX-RS, I think you actually left out the
critical parts, namely the full request method including the annotations.
That makes it difficult to help. I'm pretty sure that the PDF is
produced properly, but something goes wrong in the communication between
the browser and the server. If you stream the PDF over HTTPS, you might
want to take a look at this:
http://xmlgraphics.apache.org/fop/trunk/servlets.html#ie
What applies to servlet may easily apply to JAX-RS, too.
