Hi,
I'm trying to deploy a moderately complex WO app to a Tomcat. After
successfully
building a valid war file and tweaking the web.xml for project wonder,
I still have
one problem left. Don't suppose anyone seen this before:
Exception occurred: java.lang.NullPointerException (to be caught at:

I got the nagging suspicion, that it's got something to do with the
log4j properties,
is that possible?
