thanks, Will - I should probably go back and have another look at logging in my
default Velocity setup.
fyi/btw: I am using 1.5 ... I last thought about logging when I upgraded. I was
thinking "ah ha! this might fix that logging annoyance too!" - but it didn't :(
... so I left it alone for some rainy day.
for the record, my default setup (dealing purely with tomcat webapps here)
looks like this:
/WEB-INF
|- /classes
|- log4j.properties
|- /lib
|- ... velocity jars, commons jars, log4j jar, my jars etc ...
|- toolbox.xml
|- velocity.properties
(specifying log4j logchute with runtime.log.logsystem.class)
|- web.xml
(using VelocityViewServlet mapped to *.html and *.vm)
... and so on. All totally standard and basic - but my log4j.properties is not
used by Velocity - but it _is_ used by Spring, which I use a lot, and any
Commons Logging stuff I use in my own code. In fact, velocity is the only
library I work with regularly for which this setup does not work ... which has
always struck me as curious - but not curious enough that I have felt the need
to investigate and fix :D
