I've checked into jbossws ( https://svn.jboss.org/repos/jbossws/stack/cxf/trunk) a testcase for WS-Trust ActAs. (see list of files at the bottom.) I have not found any on-line examples that enable me to confirm this implementation is correct. It works but is it correct? Any feed back you care to provide would be appreciated. Documentation based upon this testcase and your feedback is forth coming. (I am working on another pass at code cleanup and refinement.) I do have the following question. Where does the requirement for a (JBossWS-trust-sts) security-realm for the STS come from? I do not find any discussion of this in any of our JBossWS docs or the CXF docs. Is it tied to the wsdl in some way?
