问题 I'm running a Play framework application on a VirtualBox VM with the project source code in a directory shared from the host system. The auto-reload functionality of the framework doesn't work.

问题 I started using the Playframework recently and am implementing a site using Play 2.1.1 and Slick 1.0.0. I'm now trying to wrap my head around Json Writes as I want to return Json in one of my controllers. I've been looking at several references on the subject (like this one and this one but can't figure out what I'm doing wrong.
