The problem description might be long. Please be patient and provide any kind of help since I am new to the web services.

What I have done: I have created a web service in java using Apache CXF RI. I simply created a class and used bottom up development approach to generate SEI, WSDL and XML files.

What the problem is: Now, If I request "http://localhost:8084/DeepThoughtWS/services/DeepThoughtPort/whatIsTheAnswer", it produces output as No binding operation info while invoking unknown method with params unknown. The response is as follows:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <soap:Fault>
      <faultcode>soap:Server</faultcode>
      <faultstring>No binding operation info while invoking unknown
      method with params unknown.</faultstring>
    </soap:Fault>
  </soap:Body>
</soap:Envelope>

The generated WSDL is:

<wsdl:definitions xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
xmlns:tns="http://ws.service.com/"

      <soap:address location="http://localhost:8084/DeepThoughtWS/services/DeepThoughtPort" />
    </wsdl:port>
  </wsdl:service>
</wsdl:definitions>

The DeepThought class includes:

@WebService(targetNamespace = "http://ws.service.com/", portName = "DeepThoughtPort", serviceName = "DeepThoughtService")
public class DeepThought {
    public String whatIsTheAnswer(@WebParam(name = "arg0") String interviewer) {
        return ("The answer " + interviewer);
    }
}

The console output at the time of request shows some errors too:

In general, this exception usually occurs if the incoming soap method doesn't correctly match the WSDL. In such a case, the soap message could not be mapped to an appropriate method on the service. CXF just doesn't know what to do. Double check the incoming soap message.

Source of the above explanation.

Possible solution:

@WebService(targetNamespace = "http://ws.service.com/",
        portName = "DeepThoughtPort",
        serviceName = "DeepThoughtService",
        endpointInterface = "your.pck.DeepThoughtService",
        wsdlLocation = "WEB-INF/wsdl/DeepThoughtService.wsdl")
public class DeepThought {

    @WebMethod(action = "whatIsTheAnswer")
    public String whatIsTheAnswer(@WebParam(name = "arg0") String interviewer) {
        return ("The answer " + interviewer);
    }
}

What I would do is to add the WSDL location and endpointInterface in your @WebService. Also you are using Java-First approach so your method should be annotated with @WebMethod(action = "whatIsTheAnswer"). So if the method is not annotated CXF "understands" that your web service does not contain any methods at all and says: No binding operation info while invoking unknown method with params unknown.
