JBossWS-CXF can install the spring as modules in AS7, you don't need to include them in maven dependency. Can you try to install the spring module to AS7 under jbossws-cxf-bin-dist with:
ant -Djboss.bind.address=your-address -Djbossws-integration.target=jboss711 -Djboss711.home=$AS7_HOME -Dspring=true deploy-jboss711
to see if that helps ?
