OK, thanks for the feedback, I'm glad you had it working finally.
This basically confirm that in order for building up such a spring based cxf bus for a in-container client, the imports and exports for META-INF in cxf and spring modules are required.
Now, I'm wondering if it's possible to achieve the same by setting a dependencies on the org.jboss.ws.cxf.jbossws-cxf-client module. In order for making that possible, I'll have to review the import and exports of the AS modules; will do as part of https://issues.jboss.org/browse/JBWS-3607
