Hi M,

weird exception and I have no good idea... anyway, you might want to try 
  putting the cactus libs in shared/lib instead of common/lib, and maybe 
also move commons-logging-api.jar into server/lib (I still haven't 
understood why it was put in common/lib at all).

It seems that the problem is with the logging, but I'm not sure. Here's the pertinent stack

whereas tomcat 4.1.24 comes with commons-logging-api. I imagine the problem stems from this,
but I'm not sure how to fix it. Swapping jars didn't work and produced a different exception
(when logging-1.0 is used, i get log4j errors). I'd prefer not to remove logging-api frmo
this directory, however, since I don't know what other dependencies tomcat may have with this
