Hi, I'm fairly new to Lift/Scala but like the ideas of less code writing and function passing etc. I've had a brief look at the Lift web framework but was wondering if it is at all possible to leverage pre-existing JSP Tag libraries, ideally while being able to still place/mix with Lift's snippet tags? As Scala is able to utilise norm...
