Hello! I'm developing web services using JbossWS 1.0.4.GA in Jboss 4.0.4.GA I have to implement the WS-Security. So I wrote the jboss-wsse-server, jboss-wsse-client, I updated the web.xml with the <contex-param> tags and the jboss-client with the <config-name> tag, I genarated the truststore and the keystore and I inizialized the system variables for the truststore and the keystore. When the client run, it sends a SOAP message encrypted ad it has to do (as I can see using the tcpmon). But the WS answers with a fault. It says that there is a "Unprocessed 'mustUnderstand' header element: {http://docs.oasis-open.org/wss/2004/01/oasis-200401-wss-wssecurity-secext-1.0.xsd}Security". I hope someone help me, because I'm desperate. Thanks Angelo View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4060019#...
