Tomcat 4 does not make an XML parser available to web applications - only
to internal uses. It may be that the JSPTL library requires the
availability of an XML parser in order to work.
See the Tomcat 4 release notes (RELEASE-NOTES-4.0-B7.txt in the top level
directory) for more information about XML parsers in Tomcat 4.
