Services Header (was Re: Unresolved symbols when creating WSDL2RPG Service Program)

Thanks so much for your analysis Thomas.
I hope this discussion provides a guide for other newbies.
I've actually got the whole thing working! With a lot of help from our
web services people. I am progressing but still have questions.
After our first attempt which failed, our services people discovered
that the Service Header was not included in the Soap request, and I
haven't found any reference in the list to this. We inserted the
string into the request manually and it worked. Is there something
more I have to do or should the WSDL included below have caused the
WSDL2RPG program to generate the correct request inclusive of the
Services header?
When the interface program generated by WSDL2RPG runs, it receives the
response into rtnValue. I can see the correct values through debug.
However when the procedure ends, the calling program crashes with
'Pointer not set for location'. Here is the invocation code:
tns_GetCoverOptionsResponse_t=
GetCoverOptionsPort_GetCoverOptions(
parameters:
errText);
Lastly, I also wanted to cover the last problem I raised. I've
included the xml at the end of this email.
I went back to square one to stay as close as possible to your example
code.
I've included the XML used as input to WSDL2RPG so that the following
references make sense.
I traced all the references back to obtain the names of the parameters
but when I compiled the test harness it failed with:
*RNF7030 30 008701 The name or indicator FROMDATE is not
defined.
*RNF7030 30 008702 The name or indicator PRODUCT... is not
defined.
This is on the two fields being set into parameters:
008701 parameters.FromDate= '20100324';
008702 parameters.ProductTypeCode= 'PLL';
008800 // Now let's call the web service.
008801 tns_GetCoverOptionsResponse_t=
008900 GetCoverOptionsPort_GetCoverOptions(
009100 parameters:
009200 errText);
And here is the trail of parameter declaration:
* Request message
* These fields needs to be filled with reasonable values
* right before calling the web service.
D parameters DS
likeds(tns_GetCoverOptionsRequest_t)
D inz
==================
D tns_GetCoverOptionsRequest_t...
D DS based(pDummy)
D qualified
D CoverOptionsStandardRequest...
D
likeds(ns1_RefDataStandardRequest_t)
==================
D ns1_RefDataStandardRequest_t...
D DS based(pDummy)
D qualified
D FromDate 10A varying
D ProductTypeCode...
D 3A varying
Because it wasn't compiling, I ended up changing the parameters
declaration by hand to the initial structure.
D parameters DS
likeds(ns1_refdatastandardRequest_t)
This let me compile as the 2 parameter fields were recognized.
I realize that this would have to be done every time I created the
application interface but it enables me to continue the R&D. Any
advice you have would be wonderful. I created the module and program
as per your PDF and have been able to test.
Here is the wsdl:
