Dave,I spent some time reading the source code of commons-discovery version 0.2 which I believe matches the version you are testing with. Reading the javadocs for o.a.c.discovery.tools.DiscoverClass and your previous messages, I added
the file "org.apache.commons.logging.LogFactory" under META-INF/services.
You can find the modified jar file including the fix as an attachment to this message. Can you please give it a try?

I had not modifed jcl104-over-slf4j.jar other than to add
/META-INF/services by unpacking the jar (from the 1.0 release), adding
the file and repacking.
The original, unmodified 1.0 release of jcl104-over-slf4j.jar and the
one you sent me both fail like so:

I believe that the vm is able to load
org.apache.axis.components.logger.LogFactory because javac tends to fold
public static final variables into generated code, therefore there are
no references to FACTORY_PROPERTIES and FACTORY_DEFAULT in the axis
LogFactory, just the values are stored. So I don't think they can be
overridden without recompiling axis.jar.
