That is the best way to avoid problems, so further tries should rely on that.
Maybe Tomcat 5.0.30 delivers an old commons-logging-api.jar. Have a look at
and try to find the correct combination of
a) replacing the old version with the current commons-logging inside tomcat
b) replace WEB-INF/lib/commons-logging-1.1.jar with commons-logging-adapters.jar

Force commons-logging 1.1 with JVM parameter
to give you a trace of what it does. If you still have errors - please post this trace.

Please send back your solution to the list...
