Hi All! Downgrade your JVM and your problem shall be gone. It has to do with the SOAP-implementation (SAAJ). I think you can switch SAAJ-implementation by adding a newer saajImpl.jar file to the $JBOSS_HOME/lib/endorsed directory. I'm not sure about the last part about SAAJ but it is a known problem using JBoss 4.2.x with Java 6.
