I will probably have time to do some actual tries end of this week; in the mean time, a workaround solution might be to download and install jbossws-native 3.4.1 stack on AS6.0.0.Final or jbossws-native 4.0.2 on AS 7 (check https://community.jboss.org/wiki/JBossWS-SupportedTargetContainers ).
I'm going to check the proper way of having this run with jbossws-cxf stack installed installed on AS7.
