or if the common-loging*.jar files are not added to the BootClasspath and
left in their default directories (common/lib resp. server/lib) one gets:

If one creates a verbose output of what happens in the last case ( the
ClassNotFoundException) one finds the following:

The Class LogFactory was allready found when used by the Digester if it comes to
loading the AprImpl class suddenly the LogerFactroy can't be found any longer.
The used java version is: java full version "1.4.1_01-b01"
Operating System: Linux version 2.4.10-4GB (root@ibh03) (gcc version 2.95.3

Something similar happens when trying to use the current released version
of log4j. Putting log4j.jar into the common/lib directory gives a
NullPointerException putting it into $JAVA_HOME/jre/lib/ext gives the
ClassNotFoundException from above.
