Can Web Start handle multiple XML parsers at once?

Web Start uses JAXP for parsing XML. I want to use Xerces 1.1.3. However, xerces.jar includes newer DOM classes that conflict with the older DOM classes shipped with Web Start. I also use SOAP which depends on newer DOM classes as well. When my app makes a SOAP call that uses a method available only in the newer DOM classes, Java’s runtime throws a NoSuchMethodError because it is using the older DOM classes from jaxp.jar rather than the newer ones from xerces.jar.
