ABAP calling web service provided by AXIS -error

[Former Member]

Hello expert,

I am calling web service provided by AXIS in ABAP but error occur when processing response part.

The web service is used to create material master in JAVA AXIS system.

After setting up the LP in soamanager then make a call, we got an error saying

"GENERAL_ERROR Error duing proxy processing (PART

UNKNOWN (NULL) ) "

I looked at the full trace in soamanger, the call is executed successful, and the data are inserted in the remote system.

response payload can be seen in the trace

Request payload

Response Payload

<?xml version="1.0" encoding="utf-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"><soapenv:Body><CreateITEMResponse xmlns="http://sap.env"><CreateITEMReturn>S</CreateITEMReturn></CreateITEMResponse></soapenv:Body></soapenv:Envelope>

For me it looks it is an issue in the response payload that ABAP proxy can not process it.

such as, the response payload NS prefix is soapenv, other than soap-env in request payload...

but i am not sure, whether this is the root cause.

Could you help me to find out what is going wrong here?

xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" is equivalent to xmlns:soap-env="http://schemas.xmlsoap.org/soap/envelope/" . Namespace defined correctly.

I can also see that response is correct (assuming "S" denote success):

<CreateITEMReturn>S</CreateITEMReturn>

Also check type of WSDL style usually this error occurs if you are using RPC/Encoded style WSDL, modify wsdl for Document/Literal style (as RPC style WSDL not supported by ABAP proxy), see this discussion here:

Refer to note: 1358647

Hi Gourav,

Your answer is definitely helpful and solve my problem.

I changed the WSDL style as "document/literal with wrapped" and everything is fine now.

Hi Charlie,

How do we change the WSDL style? Do you mean the WSDL provider needs to change and regenerate the WSDL again?

I have got a WSDL generated by a non-SAP system and using that WSDL, I created the proxy. When i execute the proxy, the target system receives my message and they respond back with some response. However I get the same error message (exception) that is discussed in this thread.

Hi Karthick,

In my case, Yes. The service provider should change their WSDL style and provide the "document" style WSDL.
