How can I host a single "index.html" through Jetty?
My idea is to put a webpage that calls an application with JNLP
I really don't know how to serve the page at the first place! (or if it is possible through Jetty)
Just look at your Jetty home directory structure. Something like '[YourJettyHome/]webapps/root/index.html', which is the index.html file provided by your Jetty distribution.
