Re: [EXTERNAL] Re: Question concerning Integrated Web Services

Alan,

I was suggesting removing return values from your code because I thought it'd ELIMINATE headaches.  Banging your head is only going to give you headaches.

Having a return value together with RTNPARM is like giving yourself a headache, but making it better with aspirin.   Not having a return value at all is like eliminating the headache in the first place.

Enough analogies :-)

Alan,

We're running 7.2 on this box, so I checked for PTF SI68555 (SI68556 is the 7.3 equivalent) and I do not have it installed.

Hi
Those drumbeats you are hearing - are NOT drumbeats Its me banging my
head on the desk I pulled back my service module and my service
program Removed the RTNPARM

It was
dcl-pr GetCustInf LikeDS(CustInfo)
RTNPARM;
inCstDiv packed(2:0) const;
inCstNbr packed(9:0) const;
end-pr;
and
dcl-pi GetCustInf LikeDS(CustInfo)
RTNPARM;
inCstDiv packed(2:0) const;
inCstNbr packed(9:0) const;
end-pi;

changed to
dcl-pr GetCustInf LikeDS(CustInfo);
inCstDiv packed(2:0) const;
inCstNbr packed(9:0) const;
end-pr;
and
dcl-pi GetCustInf LikeDS(CustInfo);
inCstDiv packed(2:0) const;
inCstNbr packed(9:0) const;
end-pi;

NOW it wont compile
I put the RTNPARM back in
It compiles

When it doesn’t compile - the error is
*RNF0320 30 1 Errors were found while generating the program information to
be placed in the module.

But no actual errors in the listing
So I run DSPJOBLOG to see if anything is there and all I see is Compilation stopped. Severity 30 errors found in program.

When I place the cursor on that and press F1 This is all I get

Hi Scott
Thanks for the reply

Let me give that a go and see what happens

All of this is brand new to me - exciting - but being the pathfinder
in our company - exasperating when I come across such problems and
there no one to bounce ideas off, in the next cubicle

Now I know how Lewis and Clark felt
If they got lost - they couldn’t walk into the nearest deli and ask
for directions

Wait a minute - they were men
Men don’t ask for directions

Alan,

I don't see why the identifier name matters?

To test this, I put together a quick program like this (I know the
return values aren't useful in a business context, it was just to see
if the web service worked)

**free

ctl-opt nomain option(*srcstmt) pgminfo(*pcml:*module);

dcl-proc GetStringForDivCust export;

   dcl-pi *n;
     division packed(2: 0) const;
     customer packed(9: 0) const;
     Result   char(100);
   end-pi;

   select;
   when division=1 and customer=1000;
      result = 'Data to test result here';
   when division=2 and customer=2000;
      result = 'Other test data here';
   other;
      result = 'Customer/Division not found';
   endsl;

end-proc;

Then, I deployed this web service by setting "division" and "customer"
as input, and "result" as output.

resource name: divcust
path template: /{incstdiv:\d+}/{incstnbr:\d+}

Division is *PATH_PARAM and identifier INCSTDIV Customer is
*PATH_PARAM and identifier INCSTNBR

Worked perfectly for me, no errors.   The only thing I can think of is that you're using RTNPARM and a return value rather than parameters, which seems like an odd thing to do.  Remember, the input/output of a web service comes via the URL or from a document such as JSON or XML. Why would you use a feature like RTNPARM saying "use a return value but make it really be a parameter under the covers".  That's really confusing, and there's no real notion of that concept in other programming languages, which makes this a real headache.

Just use parameters, as I have above, and this should work fine.  It did for me.

Hi Scott
Apologies - first of all - misspelt it - it should be RTNPARM Which
has nothing to do with IWS I was just having an exasperated moment
trying to go past the problem I was having where the identifier name
being swapped out
