Weird soap issue: Cannot find the dispatch method

Question

Hi,
I'm having strange problem with SOAP message.
I created a simple web service using jax-ws, wsgen, and so on. I deployed it on sun app server 9.0. I wrote client application (i'm using SAAJ 1.3) for testing. The response I'm getting is something like this:
<soapenv:Envelope xmlns:ns1="http://put/"
   xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
   <soapenv:Body>
      <soapenv:Fault>
         <faultcode>soapenv:Client</faultcode>
         <faultstring>Cannot find the dispatch method</faultstring>
      </soapenv:Fault>
   </soapenv:Body>
</soapenv:Envelope>First I thought there's a problem with webservice I created. So I downloaded soapui (www.soapui.org) for testing. I provided it with wsdl and endpoint. And web sevice seems to work corectly - response I got back was ok.
The strange part is: soap messages sent from soapui and from client application written by me seem to be identical. Both look like this:
<SOAP-ENV:Envelope
   xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:put="http://put">
   <SOAP-ENV:Body>
      <put:sayHello>
         <arg0>test</arg0>
      </put:sayHello>
   </SOAP-ENV:Body>
</SOAP-ENV:Envelope>I even sniffed packets (WinDump) sent to application server and in both cases soap message is the same. There's only a slight difference in http headers. Here's what server log contains after receiving a soap message from my client application:

Are you saying I can't just write jax-ws based web service using @WebService and @WebMethod and then, on client side, write code like this?
SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
SOAPConnection connection = soapConnectionFactory.createConnection();
MessageFactory factory = MessageFactory.newInstance(SOAPConstants.SOAP_1_1_PROTOCOL);
SOAPMessage request = factory.createMessage();
// create proper message elements
URL endpoint = new URL(endpoint_url);
SOAPMessage response = connection.call(request, endpoint);
// process response
//
