Jetty tuning for executable wars?

Hi all

I’ve got a reasonably working jruby rails app thanks to Warbler,
the built war file runs on a tomcat instance, and we run https on the
front under apache, proxying to tomcat via AJP.

the app doesn’t use a DB at all, so tomcat isn’t really earning its
keep.
Have had some success on other apps recently with

config.webserver = “jetty”

but what I’d really like is a way to serve HTTPS directly with jetty.

I can’t see a way to do that with Warbler - does anyone know if it’s
possible? if not, are there other warbler-like packagers that give you
more control over the embedded webserver options?
