CANNOT_READ_PAYLOAD error in Web Service Response

[Former Member]

Hi experts,

We are deploying a webservice on SAP PI, when we call the SAP PI webservice directly, everything works normal, and we get a response.

When we call the SAP PI web service through a different J2EE web service, the fields in response are null(though the SOAP message is received), because PI is not able to get the PAYLOAD in the SOAP request, the following error is obtained in the response.

<?xml version="1.0" encoding="UTF-8" standalone="yes" ?>

- <!-- Request Message Mapping

-->

- <SAP:Error xmlns:SAP="http://sap.com/xi/XI/Message/30" xmlns:SOAP="http://schemas.xmlsoap.org/soap/envelope/" SOAP:mustUnderstand="1">

<SAP:Category>XIServer</SAP:Category>

<SAP:Code area="MAPPING">CANNOT_READ_PAYLOAD</SAP:Code>

<SAP:P1 />

<SAP:P2 />

<SAP:P3 />

<SAP:P4 />

<SAP:AdditionalText />

<SAP:ApplicationFaultMessage namespace="" />

<SAP:Stack>Unable to read payload from the message object</SAP:Stack>

<SAP:Retry>N</SAP:Retry>

</SAP:Error>

Every other configuration and the web service settings used are the same, Only the direct call to a WEB SERVICE DEPLOYED IN SAP PI engine is redirected through a WEB SERVICE deployed in J2EE engine to the SAP PI engine, is causing problems.

Please Help..Urgently.

Thanks..

Hi,

Are both requests (plain PI and WS encapsulated) strictily identical ? If PI can not parse body when intermediate WS is invoked, it might be due to a (slight) change in the WS request (ie namespace, declaration etc) ...
