Solution

(Thanks to Keith Lea!)

It turns out Velocity's Avalon logging system was trying to write to my Tomcat folder.

So that it's on file somewhere for other people, I will describe the solution:

  • I created a file "velocity.properties" and placed it in my WEB-INF/classes folder.
  • Inside the file I wrote:
Code Block
runtime.log.logsystem.class=org.apache.velocity.runtime.log.NullLogSystem

This stops Velocity from logging, and the example application now works.
