Well, a few things.  The Velocity servlet, if left 'as-is', will take the
value of properties and use as is in the Velocity engine.  The velocity
engine, which itself knows nothing about webapps, will assume 'current
directory' for any relative pathname (of which 'velocity.properties' is one
of them.)

The solution?

Take  a look at examples/servlet_example2 and see how the init() code
figures out how to find the file relative to the webapp root.  It does the
same for file path and runtime log, IIRC.

P.s.  This is pre-coffee, so YMMV
