Aache-Java-client for .NETwebservice

["Bauer, Sandra, vpe" <Sa...@v-pe.de>]

Hello,

I've written a Java client(Apache SOAP) with JBuilder, 
which should communicate with my webservice written un C#. 
The client sends a string, which he gets over a GUI, to 
the webservice. The webservice sends back the 
message: "Hello"+string.

I call the webservice with:  
resp = call.invoke
(url , "http://localhost/EchoService/Echo");

(My namespace is called "Webservice", my Service ich 
called "EchoService" and the method is called "Echo".)

I call for the response like this:
try {
      System.out.println(url);
      resp = call.invoke
(url , "http://localhost/EchoService/Echo");
      }
    catch(SOAPException ex) {
      System.err.println("Caught SOAPException (" + 
ex.getFaultCode() + "):" + ex.getMessage());
      System.exit(-1);
      }

    if (resp != null) {
      ret = resp.getReturnValue();
      System.out.println("resp object is: " + resp);
      Object value = ret.getValue();
      System.out.println("value object is: " + value);
      try {
        System.out.println("getPartCount returns: " + 
resp.getPartCount());
      }
      catch(javax.mail.MessagingException e){
        System.out.println("Exception caught: " + e);
      }
    }
    else {
      Fault fault = resp.getFault();
      System.err.println("Generated fault: ");
      System.err.println(" Fault Code = " + 
fault.getFaultCode());
      System.err.println(" Fault String = " + 
fault.getFaultString());
      }

    String serviceResponse = value.toString();
    return serviceResponse;
    }
}

Now I get the following response:
Invoke this call: [Header=null] [methodName=Echo] 
[targetObjectURI=http://localhost/EchoService/Echo] 
[encodingStyleURI=http://schemas.xmlsoap.org/soap/encoding/
] [SOAPContext=[Parts={}]] [Params={[[name=txt] 
[type=class java.lang.String] [value="String,which I 
enter"] 
[encodingStyleURI=http://schemas.xmlsoap.org/soap/encoding/
]]}]
resp object is: [Header=null] [methodName=null] 
[targetObjectURI=null] [encodingStyleURI=null] 
[SOAPContext=[Parts={[cid:null type: text/xml; charset=utf-
8 enc: null]}]] [fault=[Attributes={}] 
[faultCode=soap:Client]

So I think, my Webservice don't undrestad the request. But 
why? Here's my webservice:
namespace SandraWebservice
{
[WebService(Namespace="http://localhost/EchoService/")]
  public class EchoService : System.Web.Services.WebService
  [WebMethod(Description="Enter a name and this Webservice 
returns 'Hello' with this name")]
[System.Web.Services.Protocols.SoapRpcMethodAttribute
("http://localhost/Echoservice/Echo", 
RequestNamespace="http://localhost/Echoservice/", 
ResponseNamespace="http://localhost/Echoservice/")]
		public string Echo(string txt) {
			return "Hello " + txt;
		}}
