Typically, SOAP services are exposed over HTTP using the POST operation. You seem to be trying to access the service using the GET operation. Also, what the JBoss WS Stack you are using and  in which JBoss AS ? You better append the request parameter , something like, ?method=Yr_Service_Method. Also, if you are using plain Http, then you can include an Http header before invoking the service. .setHeader(Exchange.HTTP_METHOD, constant("POST")) -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/806706#806706] Start a new discussion in JBoss Web Services at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
