You can try putting commons-logging.jar (not commons-logging-api.jar) in
common/lib, and see what happens.  However, this is not likely to work,
since commons-logging usually needs other classes often supplied by the
webapp (e.g., log4j-xxx.jar) in order to actually create a functional
logger - which is what's happening in your example.  Moving these other
classes to common/lib can easily conflict with Tomcat's own logging,
causing Tomcat not to run at all.  You should pick something simpler
(less dependencies) from your app to test with and move that jar or
class to common/lib.
