looks good.

you don't need this property unless you are using your own repository impl.

Depends on if you want to load it from the file system or as a String.
 I haven't actually tried the latter, but i think you simply need to
put it into the repository before you init() Velocity.   So, somewhere
before Velocity is initialized you should do:


for the former (which actually sounds more like what you want), you
simply need to have another resource loader configured.  Note that the
resource.loader property takes a comma separated list of names of
loaders that should be initialized and used.  Velocity will check the
resource loaders in the order listed until it finds the requested
file.  So, you might do:

resource.loader = string,file
string.resource.loader.class =
file.resource.loader.class =

and you can, of course, add a file.resource.loader.path property or
use a different resource loader(s) entirely.
