Hi! I read another thread on this forum having the same problem. It sounds that the SOAPAction http header is not set. Can you try to invoke the service by using SoapUI http://www.soapui.org, or enable the RequestDumperValve in tomcat's service.xml ($JBOSS_HOME/server/default/deploy/jbossweb-tomcat55.sar/server.xml). Doing so you can see all the sent request parameters, headers etc. Kind regards Oskar View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4050899#...
