Question: Application error when using SOAP sender

Question

Hi,
I got the following error when calling SOAP sender:
- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">
  <SAP:Category>Application</SAP:Category>
  <SAP:Code area="UNKNOWN">APPLICATION_ERROR</SAP:Code>
  <SAP:P1 />
  <SAP:P2 />
  <SAP:P3 />
  <SAP:P4 />
  <SAP:AdditionalText>application fault</SAP:AdditionalText>
  <SAP:ApplicationFaultMessage namespace="http://xml.apache.org/axis/">hostname</SAP:ApplicationFaultMessage>
  <SAP:Stack />
  <SAP:Retry>M</SAP:Retry>
  </SAP:Error>
The return message is:
  <?xml version="1.0" encoding="UTF-8" standalone="yes" ?>
- <!--  Call Adapter
  -->
  <ns2:hostname xmlns:ns2="http://xml.apache.org/axis/">gdcn-admin</ns2:hostname>
From the runtime monitor, it shows:
SOAP: response message contains an error Application/UNKNOWN/APPLICATION_ERROR - application fault
Actually I maintained the host name in file hosts. And with XMLSpy, I can directly connect the Webservice successfully, but with XI, it stops me at this point. It seems the connection has been established, because if the WebService is stopped, I will get error HTTP 0 Null, If it's started, I get the above problem.
Could you please provide the hints.
Thanks a lot!
Best Regards

Hi,
I found the problem:
It's because of the wrong format of message. the message is created with a WSDL file generated by external development system, but it's not correctly explained by XI. I manually created the messge (request & response), then it worked.
Actually the error has nothing to do with hostname. it means the host returns application error (but unfortunately there is no detailed information).
Thanks a lot for your kindly help!

By the way, how can I reward the point?
