Hi; JDK : 1.6.0_11-b03 Server : 5.0.1.GA I have developed an EJB3 class like this; @WebService(name="EchoWebService", portName="EchoPort", serviceName="EchoService") @Stateless @SOAPBinding(RPC) public class EchoServiceBean implement IEchoService { @WebMethod public String echo(String echo){return echo} } It is succesfully deployed in to the server, I can see WSDL file. After that I created a client using the wsconsume, it generates EchoService client code. But when I want to call the webservice via EchoService using wsrunclient --> wsrunclient MyMainMethod "Echo", it throws the following exception javax.xml.ws.WebServiceException : No Content-type in the header! What is the problem? Thanks; View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4219758#...
