Well, not really. At runtime on JBoss AS there's a MBean that gives these info or you can use a ServiceLoader to get the configured org.jboss.wsf.spi.management.StackConfigFactory which in turn can be used to the the StackConfig that has getImplementationTitle() / getImplementationVersion() methods. Things change a bit dependending on the version you're using.
Alternatively, look for the jbossws-*-client.jar. The manifest in there tells you what stack is in use and the version. Of course, there's jbossws-cxf-client.jar and jbossws-native-client.jar.
