wsdl2rpg.sh takes a WSDL, and generates C programs, and RPG stubs to call the C programs, so that you can call the web service from RPG.

There is a whole manual on this tool.  IT should answer just about any question you might have:

Also, here is a tutorial that walks you though the process of using wsdl2rpg using a simple example:

Hi Gary,

Found a WSDL on "http://currencyconverter.kowabunga.net/converter.asmx?WSDL",
it's not 100% the same but I was able to create a test program.

It's not working yet, but I understand the idea :-)

Hi,

The only response I get from the WS-Call is an error:
"HTTPTransportException: HTTP transport error.■Server sent HTTP error: 'Forbidden'■"

Because I am able to get a response from WS with SoapUI it isn't a protected server.
It was possible to grab the wsdl from this server with wsdl2rpg.sh, so I assume it is also not a authorization issue on the AS/400.

Is there any log available where I can find the details about this error?

You connected to a remote HTTP server.  It understood the request, but it responded "Forbidden", indicating that you attempted to access an asset or service that you weren't authorized to.  Usually this means that there are server-side authentication requirements that you have not met, or your URL is not quite right.

https://httpstatuses.com/403

The relevant log would be on the server.  If you want client-side logging, you'd have to write that.  Suggest you debug and view the url and request you are constructing.

Please post your code, and the working SoapUI request.

Hi Gary,

The stubs are generated from url : http://currencyconverter.kowabunga.net/converter.asmx?WSDL

The result of the attached RPG  is:
WS_DS.HANDLE = SPP:0000800047154DD0
WS_DS.EXCOCCURRED = '1'
WS_DS.EXCCODE = 51    
WS_DS.EXCSTRING =  HTTPTransportException: HTTP transport error.■Server sent HTTP error: 'Forbidden'■                                          

RPg-Line 19  "stub_create_ConverterSoap(ws_ds);", retuns a True,
I get an WS_DS.HANDLE value, so that seems to be correct (and available).

The attachment with SoapUI data contains the expected result.
Test_Rpg.txt
Test_SoapUI_xml.txt

The 'Forbidden' problem is not solved yet, but I was able to call a few services from our own iServer.
But I really need to caal external services, so I tried an other one.

The result is now:
HTTPTransportException: Cannot initialize a channel to the emote end.■GSKit Error is 202 - Key database file was not found.

I understood that it is a certificate issue (far beyond my kowledge-area)
So I copied an example and it seems to do something.
axiscStubSetSecure(ws_ds.handle:'/QIBM/USERDATA/ICSS/CERT/SERVER/DEFAULT.KDB':'':'':'NONE':'NONE':'':'':'':'true');

the new error is:
HTTPTransportException: HTTP transport error.■Server sent HTTP error: 'Bad Request'■                                    

Because I dont know what I am doing, nor what the SetSecure is doing for me, I have really can't no idea what is wrong.
Could be data, could a certificate or something else.

HTTPTransportException: Cannot initialize a channel to the emote end.■GSKit Error is 202 - Key database file was not found.

Looks like you're trying to connect to a service that requires SSL, but you didn't configure for SSL.

Then you called SetSecure to provide the local certificate database

axiscStubSetSecure(ws_ds.handle:'/QIBM/USERDATA/ICSS/CERT/SERVER/DEFAULT.KDB':'':'':'NONE':'NONE':'':'':'':'true');

Now you are successfully connecting, but you are sending an invalid request to the web service host.  

If you can provide a trace log (mask out anything private), we might be able to provide more help.

Hi Gary,

How can I make (or where can I find) a trace log?

Hi Gary,

The function axiscAxisWriteTrace() is not available in RPG, but axiscAxisStartTrace() is logging the whole process, and pointed me to the right direction.

I couldn't find this in the manual, but  defining a Data-structure with LikeDs(), from a imported template,  is requiring an inz option.
Without that, the result is unpredictable.

SO the first WS is running 10 other to go :-)

THANKS!!!!!!!!

Thanks for this fast solution/response.

Happy to help.
