You don't identify what servlet container you're using, but most
containers provide an XML parser for use by web applications already, so
you don't need to include one inside the webapp. Including *part* of a
parser (i.e. just one of the JAR files) is guaranteed to give you class
loader problems like the one you observed.
Note that none of the Struts webapps include an XML parser, yet they all
use Digester to parse the configuration files.
