hmm. i suppose the VelocityViewServlet is really the only "concrete" public
example using the WebappLoader (that i know of).

these look fine to me. but, you do also need to put the ServletContext into
velocity's application attributes (see below) so that the WebappLoader has a
way to actually load things.

well, you look at the log output and/or just see if it works... not sure
what you're hoping for here...

you need to manually put the ServletContext into the app attributes before
the WebappLoader is initialized (i.e. *before* Velocity.init() gets called).
it might look something like:
Velocity.setApplicationAttribute("javax.servlet.ServletContext",
myServletContext);
Velocity.init(myProps);
you might also look at how the VelocityViewServlet does it.

no, RuntimeSingleton.getTemplate("foo.vm") should use the configured
resource loader automatically.
