RE: External RE: Web Service Return DS Array -- RPG400-L

That is something outside my understanding and will dig into that further.

If I needed at add an another array wouldn't I just add them with another _LENGTH field?

No idea how to make IWS do that automatically.

Here is my current code.

// ===================================================================================
// Data Stuctures
// ===================================================================================

Dcl-DS Response Qualified Template Inz;
Type Char(2);
Description Char(40);
End-Ds;

// ===================================================================================
// Input Parameters
// ===================================================================================

Dcl-pr WOMConTypR;
Envir Char(2);
Responses_LENGTH Int(10);
Responses LikeDS(Response) Dim(50);
Fail Char(100);
End-pr;

Dcl-pi WOMConTypR;
Envir Char(2);
Responses_LENGTH Int(10);
Responses LikeDS(Response) Dim(50);
Fail Char(100);
End-pi;

And suppose the requirement chages so that you need elements after the array. Or two separate arrays, Now your code is more fragile because any change requires a check on the math.

As I said - IWS has a built-in capability to handle this - I'm surprised that Amra didn't mention it.

I am setting the Length in the pgm after all elements are loaded.

SetLL ('COMMENT TYPES' : 'CONTACTS') Param;

Or Idx = %Elem(Response);

EndIf;

Idx = Idx + 1;
Responses(Idx).Type = PmKey3;
Responses(Idx).Description = PmText1;

EndDo;

Responses_Length = Idx;

Is this IWS you are using for deployment? I'm guessing but in future if it is please say so.

If so a better way than setting the response length (which will cause you ongoing maintenance issues) is to have your routine return a count of the number of elements and tell IWS to use that to control the output.

I can't point you at any articles or anything but the approach is detailed in a presentation that I give. If you email me direct I'll gladly send you a copy.

I did get that working.
Data in pgm looks good.

The service is getting back blanks so need to figure out what I have wrong.

{
"RESPONSE": [],
"FAIL": ""
}

Hi,

Try something like that :

Dcl-pr WOMOrdTypR;
Envir Char(2);
data likeds data_t dim(20);
Fail Char(100);
End-pr;

Dcl-pi WOMOrdTypR;
Envir Char(2);
data likeds data_t dim(20); Fail Char(100);
End-pi;

dcl-ds data_t template ;
Type Char(2);
Description Char(25);
End-ds;

Hi All

Cross posting to Web list as well.

In my current pgm that is called from my Web Server I return arrays for each element.

I want to return a DS array instead.

Current Parameters

Dcl-pr WOMOrdTypR;

Envir Char(2);

Type Char(2) Dim(20);

Description Char(25) Dim(20);

Fail Char(100);

End-pr;

Dcl-pi WOMOrdTypR;

Envir Char(2);

Type Char(2) Dim(20);

Description Char(25) Dim(20);

Fail Char(100);

End-pi;

Which returns this from the service

{

"TYPE": [

"DS",

"EX",

"LT",

"NC",

"RM",

"RW",

"SL",

"",

"",

"",

"",

"",

"",

"",

"",

"",

"",

"",

"",

""

],

"DESCRIPTION": [

"Drop Ship",

"Expedited Order",

"Literature Packed",

"No Charge",

"Remake",

"Re-Work",

"Standard Lead",

"",

"",

"",

"",

"",

"",

"",

"",

"",

"",

"",

"",

""

],

"FAIL": ""

}

I want it to return

[

{

"TYPE": "DS",

"DESCRIPTION": "Drop Ship"

},

{

"TYPE": "EX",

"DESCRIPTION": "Expedited Order"

},

{

"TYPE": "LT",

"DESCRIPTION": "Literature Packed"

}

]

How do I define this as a DS so the service returns what I want?
I am looking for some good documentation on templates, I am assuming this is what I want but have never used it.
