PI WS Adapter not working

[Former Member]

We are are trying to perform an IDOC to web service integration. I have tested the service using the SOAP adapter and it works however we are required to use the WS adapter which we cannot get to work. We have also tested the web service enpoint with SOAP UI and also the webservice tester in Netweaver.

The error we are seeing is:

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

- <!-- Call Adapter

-->

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

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

<SAP:Code area="INTERNAL">WS_ADAPTER_SYS_ERROR</SAP:Code>

<SAP:P3 />

<SAP:AdditionalText />

<SAP:Stack>System error while calling Web service adapter:</SAP:Stack>

<SAP:Retry>M</SAP:Retry>

</SAP:Error>

I have seen some other posts relating to a similar problem however they all appear to have an actual error message after "System error while calling Web service adapter:"

Has anyone seen this error or alternatively shed some light on this problem?

Thanks for the quick reply.

The webservice endpoint is on a webMethods server, I could not see any documentation saying that the WS adapter cannot communicate with a non SAP web service.

Although we can use the SOAP adapter we would prefer not to as it does not implement the web service standards such as reliable messaging out of the box.

Yes it requires the end system to support RM for it to work.

Is there any setting on the WM server perhaps that needs to support RM protocal?

WS Adapter is meant for Web services exposed out of SOA Manager on an ECC system. I hope that's the kind of web service you are inteegrating with. If so refer the following link
