When using/calling a JAX-RPC client stub inside the AS I get the following exception:

jboss ClassCastException: org.apache.xerces.dom.ElementNSImpl

I was able to temporarily fix this by adding in a system property to use a different implementation of MessageFactory (sun's implementation
javax.xml.soap.MessageFactory=com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl

However when this does not work when trying to also use jax-ws web services on the same server as jboss implementation code throws a class cast exception because it cannot cast one of its classes to com.sun.xml.messaging.saaj.soap.ver1_1.SOAPMessageFactory1_1Impl.

Is there a fixed version of the jboss saaj implementation that I can put into 4.2.3 such that I do not need to use sun's MessageFactory implementation to use jax-rpc generated client stubs within the appserver?
