The mentioned tutorial is quite old ( it references JBossWS 2.x ... )
We do have multiple maintained samples in the sources (see jbossws-native testsuite for instance) that use WS-Security and that you can take a look at.
One of them also comes with a tutorial-like documentation, see http://community.jboss.org/wiki/JBossWS-Securityandattachmentssample .
Besides that documentation available at [1] and [2], there're also many user forum discussions on the topic, for instance the one listed above: http://community.jboss.org/message/338346#338346
