Ryan, while the issue with Resin's parser is sorted out, you can use
the built-in XML parser in Sun's JVM. There is a comment in the
web.xml that shows how (so you need to explode the WAR and edit the
web.xml).
<!-- Uncomment if you are trying to use a Resin version before 3.0.19.
Their XML implementation isn't entirely compatible with Xerces.
Below are the implementations to use with Sun's JVM.
<system-property javax.xml.xpath.XPathFactory=
"com.sun.org.apache.xpath.internal.jaxp.XPathFactoryImpl"/>
<system-property javax.xml.parsers.DocumentBuilderFactory=
"com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl"/>
<system-property javax.xml.parsers.SAXParserFactory=
"com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl"/>
