You are doing nothing wrong - I do the same thing, but take care of the
'relative' path problem in one of two ways :

1) jar the template directory and put that jar into WEB-INF/lib, and
then use the classpath loader.  That should solve it right off.

2) You can convert the relative path to an absolute one by overriding
the VelocityServlet method 

   protected Properties loadConfiguration(ServletConfig config )

and either do something like

  Properties p = super.loadConfiguration( config );

   // and now use  config.getServletContext().getRealPath()
   // to convert the relative path in the properties to the realpath

or load the properties yourself from the file and do the same thing with

You should do the same thing with your logfile as well.  Any relative
path :)

I think that is just what I described...

The easiest way is with the Classpath loader, but you still have the
problem of the logfile...
