Re: HTTPAPI - Passing XML-file as Parameter to a WebService
Jan,
My best bet is that you need to encode "xmlInput" properly before you
assign it to element <_P0XMLINPUT>. For example "<" should be encoded to
"<".
The way you do it works only for elements of type "xsd:any". "any" means
that the element can contain any other valid XML elements. But in your case
I assume that "_P0XMLINPUT" is of type "xsd:string" which requires proper
encoding of XML entities.
Feel free to check the following links:

Hello,
I have a Webservice with this wsdl:
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:xsd="http://kis14tra.wsbeans.iseries/xsd";>
<soapenv:Header/>
<soapenv:Body>
<xsd:kis14tra>
<xsd:args0>
<xsd:_P0RESULTAT>?</xsd:_P0RESULTAT>
<xsd:_P0XMLINPUT>?</xsd:_P0XMLINPUT>
</xsd:args0>
</xsd:kis14tra>
</soapenv:Body>
</soapenv:Envelope>
I use the Integrated Webservice (IWS) to implement the Service. As
P0XMLINPUT I want to pass this XML as a string:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<Transportimport ISHOP="9XX">
<Kunde Nummer="9893" NummerERP="373049" />

<Farbe>100</Farbe>

</Transportimport>
I use this program and HTTPAPI to test the webservice:

My problem is, that the input parameter is empty, when it reaches the
webservice.
If I use the test-function, that comes with the IWS
(chwemag1:2001/HTTPAdmin) the service works all-right:

</Transportimport></q0:_P0XMLINPUT></q0:args0></q0:kis14tra></soapenv:Body></soapenv:Envelope>
Result:

If I use just a simple text-string as input, it works fine too. It looks
like the XML-file is the problem.
What do I do wrong? Can I user another http-function or other parameters?
Best regards
Jan
