Hi Chris,
Thank you for the responses, yes those both help. I did a lot of reading
yesterday and was unable to get a clear answer at how this should be done
with JEE, where internal resource files are expected to reside (besides
just generally being under WEB-INF) within the deployment, and the String
value that should be given to ClassLoader.getResource(value) to be able to
look them up. Hence why I reached out to the mailing list.
I have in fact created a properties directory under WEB-INF/classes, for
organizing purposes, and ClassLoader.getResource("properties/xyz.txt") does
appear to be working.
Thank you, Doug
