Hi Dan,
I've done some extensive testing (lately) with logging and Tomcat 4.x.
Make sure there is ONLY ONE jar for commons-logging in the common/lib.
Remove it from the server/lib
This should make it work. One notable exception, as I have posted on dev,
is that you may or may not get the class name logged correctly inside of
tomcat...nonetheless...you can get it to work.

java.lang.NullPointerException

Please respond
to "Jakarta
Commons Users
List"
I'm getting a NullPointerException thrown when I boot up one of any Tomcat
base instances. The odd thing is is that it doesn't throw the exception as
long as I'm running Tomcat from $CATALINA_HOME\webapps\ROOT but will if the
Tomcat instance is running from $CATALINA_BASE\webapps\ROOT
where $CATALINA_HOME=C:\jakarta-tomcat-4.0
and $CATALINA_BASE=C:\contexts\fooHere's the stack trace:
Anyways, it seems to originate from the commons-logging package and the
author of the security filter, which implements the logging, also suggested
the bug lies in commons-logging. Any thoughts? Here's the stack trace
that
appears in my localhost_log:

Anyone know what's going on here? I'm using TC 4.0.4, j2sd1.4.0_01,
win2000.
The security filter is a project from sourceforge.net and is a psuedo
container managed security system.
Thanks.
Dan
