Error .NET calling SAP XI web service

[Former Member]

Hi,

When I do a simple web service call from a Visual Studio .NET 2005 generated Proxy, it works. But if I want to use WSE3 and change the class of the service proxy from SoapHttpClientProtocol to WebServicesClientProtocol. (like descriped here: <a href="http://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/docs/library/uuid/121b053d-0401-0010-539f-f9295efb7bad">Creating a .NET Client for a SAP Java Web Service</a>)

I got the following error:

<SOAP:Fault>
´ <faultcode>SOAP:Server</faultcode>
  <faultstring>System Error</faultstring>
  <detail>
    <s:SystemError xmlns:s="http://sap.com/xi/WebService/xi2.0">
      <context></context>
      <code>PARSER.</code>
      <text></text>
    </s:SystemError>
  </detail>
</SOAP:Fault>

(SystemError has xi2.0 namespace??? but we use xi3.0)

I tried to find out where's the problem by manipulating the soap requests from .NET. The SoapHttpClientProtocol doesnt transfer any soap:Header and the WebServicesClientProtocol class transfers the following header:

<soap:Header>
  <wsa:Action>http ://sap.com/xi/WebService/soap1.1</wsa:Action>
wsa:MessageID>urn:uuid:2dc3c344-b97a-4933-9cca-f15be54e6c45</wsa:MessageID>
  <wsa:ReplyTo>
    <wsa:Address>http ://schemas.xmlsoap.org/ws/2004/08/addressing/role/anonymous</wsa:Address>
  </wsa:ReplyTo>
  <wsa:To>http: //server:8000/sap/xi/engine?type=entry&version=3.0&Sender.Service=DOT_NET_Webservice&Interface=http://www.server.com/xi/dotnet3/00^MI_DOT_NET_SECURE_SERVICE_Sync_Out</wsa:To>
  <wsse:Security>
    <wsu:Timestamp wsu:Id="Timestamp-10358da0-25cd-41f9-a55c-2901422450c8">
      <wsu:Created>2007-07-04T14:59:46Z</wsu:Created>
      <wsu:Expires>2007-07-04T15:04:46Z</wsu:Expires>
    </wsu:Timestamp>
  </wsse:Security>
</soap:Header>

I found out, that the following header also causes the same error:

<soap:Header>
  <wsa:test></wsa:test>
</soap:Header>

but this header causes no error:

<soap:Header>
  <test></test>
</soap:Header>

It looks like SAP XI has problems with the namespaces in the header.

What i have to do to call a SAP XI web service with Microsoft WSE3.

thank you

Thomas,

I read in the previous threads, that for this issue you have to overwrite the WSDL with version 3.0 namespace.I'm not sure whethe it will work or not But u can give a try.

Best regards,
