DTD encountered in SOAP context -> error in WSP response rule

  • 1.  DTD encountered in SOAP context -> error in WSP response rule

    Posted Thu July 23, 2020 10:56 AM

    There is one web service proxy component that is making call at the end of request rule to an external webservice(separated by a firewall) that is supposedly returning SOAP response. But the response rule in the WSP is failing with below error as seen in system logs-

    'wsgw (WSPName): DTD encountered in SOAP context'

    'Implied action Parsing input as SOAP, attempt pipeline. failed: DTD encountered in SOAP context at line 1 of..'

    'DTD encountered in SOAP context at line 1 of...'

    Can we confidently say that the external service is not returning a valid SOAP response data to WSP, hence this error? is there any other possibility/scenario for this particular error to occur?

    Yes:

    https://www.w3.org/TR/2007/REC-soap12-part1-20070427/#soapenv

    "The XML infoset of a SOAP message MUST NOT contain a document type declaration information item."
