SAP Webservice returning HTML response instead of SOAP

Question

<br>Hi,
I want to call a webservice created from an SAP function in SAP 6.40.
When I test this webservice with the TCPGateway tool, if no application exception occured, I receive the correct response : the <b>SOAP</b> response message:
<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
   <soap-env:Body>
      <n0:ZWsCreateWagonResponse xmlns:n0="urn:sap-com:document:sap:soap:functions:mc-style">
      </n0:ZWsCreateWagonResponse>
   </soap-env:Body>
</soap-env:Envelope>
<br>But if an application exception occured in the web service, I receive the response message in <b>HTML</b> :
500 Internal Server Error
Error when processing your request
What has happened?
The URL .../sap/bc/srt/rfc/sap/z_ws_create_wagon was not called due to an error.
The following error text was processed in the system LSD : Exception condition "ALREADY_EXISTS" raised.
The termination type was: RABAX_STATE
The ABAP call stack was:
Function: Z_WS_CREATE_WAGON of program SAPLZ_WS_HU
Form: EXECUTE of program CL_SRG_RFC_PROXY_CONTEXT ---- CP
Form: IF_SOAP_APPLICATION_RT EXEC_PROCESSING of program CL_SOAP_APPLICATION_RFC ---- CP
Form: EXEC_PROCESSING of program CL_SOAP_RUNTIME_SERVER ---- CP

Form: EXEC_PROCESSING of program CL_SOAP_HTTP_EXTENSION ---- CP
Form: HANDLE_REQUEST of program CL_SOAP_TRANSPORT_EXTENSN_ROOTCP
Form: HANDLE_REQUEST of program CL_SOAP_HTTP_EXTENSION ---- CP
<br>When I call the web service in XI with a SOAP Receiver Adapter, I get the following exception (in case of application exception but also when no application exception occured) :
com.sap.aii.af.ra.ms.api.DeliveryException:
<br>invalid content type for SOAP: TEXT/HTML
So, my questions:
- how to receive a SOAP response instead of an HTML response in case of application exception in the web service ?
- why do I get an Invalid content type exception when the response is well a SOAP response ?
<br><br>Thanks in advance,
Laurence

Answer 1

Thanks for your response, Sandro.
The webservice which I use has been modified. Now if it throws an exception, I receive well a SOAP message :
<soap-env:Envelope xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/">
   <soap-env:Body>
      <soap-env:Fault>
         <faultcode>soap-env:Client</faultcode>
         <faultstring xml:lang="en">ALREADY_EXISTS</faultstring>
         <detail>
            <n0:Z_WS_CREATE_WAGON.Exception xmlns:n0="urn:sap-com:document:sap:rfc:functions">
               <Name>ALREADY_EXISTS</Name>
               <Text>Virus scan profile /SIHTTP/HTTP_UPLOAD is not active</Text>
               <Message>
                  <ID>VSCAN</ID>
                  <Number>033</Number>
               </Message>
            </n0:Z_WS_CREATE_WAGON.Exception>
         </detail>
      </soap-env:Fault>
   </soap-env:Body>
</soap-env:Envelope>
About the exception managing :<br>
- In my integration process, I include the send step in a block, with property <i>Exceptions</i> =
ALREADY_EXISTS
- In the send step, in property <i>Exceptions</i>, I add <i>System Error</i>
ALREADY_EXISTS
- I insert an <i>Exception Branch</i> in the new block, <i>Exception Handler</i>
ALREADY_EXISTS
Is that correct?
Do I need to use Fault messages?
And how do I get the error message ?
<br>In transaction ST22, I have no dump.
<br>If it is a problem of exception managing, why do I get also the error (<i>com.sap.aii.af.ra.ms.api.DeliveryException: invalid content type for SOAP: TEXT/HTML</i>) when all is right in the web service call ?
