I am new to webmethods and trying to explore HTTP post scenario. we are planning to integrate ariba with webmethods. Ariba provides a cXML DTD.
I have created documenttype using a cXML DTD and created a flow service which has input and output referring to this new document type. I add Invoke option and selected pub.http.post flowservice. Now in the pipeline screen when I try to map the cXML node to body of http post. I read the body data should go to “String” elemnet under “data” node. But when I map it I get the attached error.
