That shouldn't be a problem. As long as you have log4j and commons-logging
in both the server and client classpaths, you should be fine.

I don't see why separating them should make any difference? Just do as I
recommend above. And remove the "transient" from your logger definition,
if you haven't already. As I said previously, it's already static. I'm
surprised that the VM allows you to define something as both static and
transient. I don't know if it is innocuous or would produce odd behavior?
