I do it this way myself to avoid the path issue, although I do sometimes us
the file loader as well.

Yes - Velocity will put the runtime log in the 'current directory' by
default.  So you can either change this by setting "runtime.log" before
init(), or do something completely different, like use a custom log class
(See the log example in /examples..)

You're going to end up getting pissed at your software
anyway, so you might as well not pay for it. Try Open Source.
