Subject: HTTPAPI (Web Service) sending an XML string as an input parameter to the service

   I was wondering if someone could help to to debug a problem that I'm
   having in working with the HTTPAPI tool and trying to consume a web
   service from the iSeries.
   This is a rather lengthy problem, but essentially I'm trying to
   consume a web service from an RPG on the AS400. Within that SOAP
   message that I construct, instead of having regular parameters (like a
   name or address etc.), I'm having to send an XML message. I understand
   that the XML message that I'm trying to send must be enclosed within
   the <![CDATA[ xml message ]]> delimiters. therein lies part of the
   problem. It appears the web service service needs me to use UTF-8
   encoding and when I attempt to send my message, I get back an error
   that the straight bracket [] characters are unrecognized. Obviously
   this is an issue of the request coming from an iSeries which is
   EBCDIC. I've tried several variations and combinations of encodings
   like UTF-8, UTF-16, ISO-8859-1 and EBCDIC. I've also tried replacing
   the [] characters in my string with the HTML representations of &#91;
   and &#93;, but to no avail.
   I'd be more than happy to send you the RPG source code that I've been
   working with as well as any other supporting information like the WSDL
   etc.
   Sincerely (and somewhat frustrated),

   BTW, here's what the entire SOAP message is 'supposed' to look like. I
   developed and tested this using the SoapUI v3.0.1 tool. When sent from
   this tool, this message works perfectly. But when sent from the AS400,
   it fails.
