setProperty must be overridden by all subclasses of SOAPMessage

Hi,
Deploying from Netbeans 6.5 and I'm running Jboss on WinXPsp2 and here is what is echoed to the screen during JBoss server startup:
Java version: 1.6.0_11,Sun Microsystems Inc.
JBoss [Trinity] 4.2.3.GA (build: SVNTag=JBoss_4_2_3_GA date=200807181417)
jbossws-3.0.1-native-2.0.4.GA (build=200803312044)
JBossWeb/2.0.1.GA

I have a webservice and a webservice client deployed on the same server. The webservice was deployed without errors but when trying to
invoke that webservice from a client I get setProperty must be overridden by all subclasses of SOAPMessage (stack trace attached to end of this comment)

I read the previous posts about copying jboss-jaxrpc.jar, jboss-jaxws.jar & jboss-saaj.jar, I tried that but I got another error about javax/xml/ws/spi/ServiceDelegate21 not found. I removed the three files above to capture the following exception:
