Re: [EXTERNAL] Re: Question concerning Integrated Web Services -- MIDRANGE-L

Hi Alan,

Your modified procedure declaration still includes a return value, unlike Scott K's example. Scott's procedure has no return value, just an additional parameter named "Result" which is then specified as an output parameter to IWS.

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
