Hi Stefan, implementing WS-Trust in JBossWS-Native is not an option at all. JBossWS-CXF is the way to go for WS-* right now. I didn't look in details at the Metro implementation of WS-Trust, but even if I think that might even be complete and interesting from a JBossWS community point of view, I think the integration with the CXF stack should be considered first. This might even be something we focus on in the collaboration with CXF. View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4228729#...
