Re: WSDL2RPG or not?

I found a post from Thomas in 2012 saying WSDL2RPG didn't handle attributes
and that the generated section of code would need to be modified...

Don't know if that's still true. I've never actually used it myself in
production, just looked at it years ago. Ended up not using it since it
didn't support something I needed (think it was related to NULL/NIL or
something)

If you've got a working, hand-coded program using HTTP API directly, I'd
just go with that.

Jon,

I think I'm running into something like that with WSDL2RPG (the Thomas
Raddatz version)... At least I can't seem to find "how to" do something in
the sample code.

I parred down the methods to 3 (from 30+) so the modules would actually
compile. I still need to get one of them compiled. Looking in the source
code, I can't see where to set element "attributes".

In my case, the element <LabelRequest> contains variable attributes like:

<Label Request
Test="YES"
LabelSize="4x6"
ImageFomat="ZPLII"
Etc..

I used the WSDL2RPG tool to create a sample/test program over this method
(GetPostageLabel), but I can't find where to set/change these attributes in
the code anywhere.

FWIW - I coded a test request using only HTTPAPI, with the SOAP message as
an RPG variable. Response time is very fast compared to a Java application
called from the same RPG pgm.

So many of the elements in this one request are "optional"... Currently,
I'll need only use 2-3 methods. Of course, that could change - but I've
been told this API will be replaced in coming years with a REST API (this
is for Endicia that was purchased by Stamps.com)

In your opinion (everyone's opinion welcome) - should I continue with
WSDL2RPG or code from scratch for my immediate needs?

Thanks,
Greg

Why?

It doesn't have the flexibility of HTTPAPI and doesn't run as quickly in
most cases - I suspect because of the underlying use of Java. Once/If IBM
get round to using C/C++ routines under the covers it may improve.

It has other downsides although I don't recall all the details. I seem to
remember that authenticating to some kinds of service was one of the issues.

To each their own - I was using HTTPAPI long before SQL offered these
options. I also use Python and PHP for this purpose - not not when RPG is
in charge of the process.

Next question (remember, this is all new ground for me so the questions
are pretty low-level):

Wouldn't one use json_table() today?

From working code:

****

**exec sql select * into :wCity, :wCountry, :wID from
json_table(systools.httpgetclob(:URL, ''), 'lax $' columns( CITY
varchar(50) path '$.name', COUNTRY varchar(2) path '$.sys.country', ID
dec(10) path '$.id') empty on error); **

That is what he was talking about Booth.

Most think of IWS as the Server part. WSDL2RPG is the client side.
