The underlying reason for the error is that your JAXP impl is too old to
support the DBF setSchema method. Someone else had a similar issue here:

You need to configure your JRE's XML parsing environment to use a newer,
supported version of a JAXP implementation (e.g. Xerces). You mentioned
Coldfusion, but didn't mention what container/app server you are using
(JRun vs. Tomcat, JBoss, etc). You most likely just need to use your
container's defined method of endorsing classes and endorse a newer
version of the Xerces and Xalan jars. We ship known, good versions of
those in the OpenSAML distribution.
