A way you can get the Servlet context is like this:
LiftRules.context match {
case context: HTTPServletContext => // do something with
context.ctx which is the javax.servlet.ServletContext
case _ => // do something when the context is not a servlet
context, perhaps log an error
}
The reason you need the match is because Lift can run on non-servlet
web containers, so Lift does not guarantee there is a Servlet context
in scope.
Hope that helps,
