Gisbert,

WDSC can not help you, since it can not generate an RPG client stub for a given WSDL file. All it can do is generate a Java client stub for a given WSDL file but no RPG.

However you may want to have a look at gSOAP which is a free utility dedicated to generate C client stubs and/or server skeletons. I don't think you want to go to C, right? Nevertheless gGOAP can help you since it also can generate sample soap messages. Forget about the C stuff and just take the sample message.

You can get gSOAP here: http://www.cs.fsu.edu/~engelen/soap.html

Given that you installed gSOAP into directory "gsoap-win32-2.7" you have to run the following commands to get the sample messages:

1) create a "temp" directory in "gsoap-win32-2.7"
2) open a DOS box and go to "gsoap-win32-2.7"
3) run wsdl2h to produce a special gSOAP header file

wsdl2h -otemp/KonverterPsKw.h http://localhost:9080/WS1UmrechnenPSinKW/wsdl/KonverterPsKw.wsdl

-o : output file = temp/KonverterPsKw.h

4) run soapcpp2.exe to create the C stub and the sample SOAP messages

soapcpp2.exe -C -L -Iimport -dtemp temp/KonverterPsKw.h

   -C  :  generate client-side code only
   -L  :  don't generate soapClientLib/soapServerLib
   -I  :  use path(s) for #import
   -d  :  use path to save files

Here is what you will get:

Hope this helps.

Hi there,

I started using LIBHTTP by working with examples 14 and 16 (requesting a web service) . I succeeded in creating a modified version to request a simple internal web service.
In example 16 the XML file content is hard-coded (fields "access request" and "track request"), which might be error-prone.
Instead I would like to be able to use the WSDL file of the requested web service in order to create the XML file content automatically,
so that I can use it in my RPG program..
I understand that WDSC is able to do that for me, but that tool is so complex, I don't know where to start (without training).
is there a simple way in WDSC or outside of it to use a WSDL file to create all the XML file content? Can XML Toolkit for iSeries do that for me?
We will switch to V5R3 in April.

Thank you.
