I want to use the Jakarta commons digester xmlrules package to parse the
xml I get from a web service I access from within a service.  This means
I have to include four commons jar files within the classpath tomcat
uses commons-digester, commons-logging, commons-beanutils and
commons-collections.  I tried putting the jar files in my CLASSPATH
variable, but Tomcat builds its own classpath, so when the servlet
executed I got a
java.lang.NoClassDefFoundError.  Tomcat (or the servlet) couldn't find
org/apache/commons/digester/xmlrules/DigesterLoader.

I am using Tomcat version 4.1.24.  There is a version of the
commons-digester jar file that comes with that tomcat in server/lib.  So
I put the commons-digester.jar file in server/lib in the commons/lib
directory so that Tomcat would include the jar file in its classpath.
However, when I did that, Tomcat wouldn't even start--the error message
then was ClassNotFoundException.  The relevant part of the stack trace
is included here below.

What gives?  It looks like the version of commons-digester.jar that
comes with tomcat 4.1.24 isn't even compatible with it, but that can't
be right?  I suppose the bigger question, though, is how can I get
Jakarta digester and tomcat 4 to play nice with each other?
