Does HIbernate package log4j.properties in their library? Where do
you put your modified log4j.properties? Log4j auto-configures itself
in a static initializer and looks first for log4j.xml and then
log4j.properties (if the former isn't found) in the default
package. Are you sure your modified version is being found instead
of the unmodified version (or even some other Log4j config file in
the classpath)? Where do you put log4j.jar? Where do you put the
hibernate library? Are hibernate.jar and log4j.jar in a shared
classloader or in WEB-INF/lib? Is your config file in
WEB-INF/classes or a shared location?
These are all things to look into. I would hasten to bet that your
modified config file is not being utilized. By answering the
questions above, and thinking about how classloaders work (taking
into account Tomcat's child-first webapp classloader), you should be
able to solve the issue.
