No Nagendran, you cannot use getJSON() and achieve this. getJSON() isn't aware of property qualifiers.

Hi Praneeth ,
We have a property named CustomerID , but the client is expecting field to be CustomerId in response. so when generating the JSON response I need the tag to be CustomerId not CustomerID.
Thanks

It's been a little bit since I've used 7.1.7 and I can't recall if it uses the same mechanism, however are you able to add pzExternalName manually and test if that has the desired effect?

I don't see pzExternalName in 7.1.7 , but this article(SA-14881) says it is a OOTB property qualifier . Not sure if it is added in 7.1.8. is there any other way to achieve this ?

Yes, the property qualifier pzExternalName was added in 7.1.8. But we recently ported this fix to 7.1.7. You could take this hotfix.

Hi ,
I installed the hotfix and added pzExternalName in property qualifier but it did not work. Still the Json response is generating with propertyname and not with the value given in propertyqualifier value.

please find the screen shot and response generated
"CustomerCase": [
{
"AgreementId": "1E571B850B6B03208D00005056A74B06",
"AssetId": "1E571B850AAA05308D00005056A74B06",
"ClientAccountId": "1E571B85091500D08D00005056A74B06",
"CustomerCaseId": "1E5AE757605107809AE9005056A74B06",

"IncidentType": "DAMAGE",
"StartDate_str": "20151229T214521.797 GMT",
The response should contain StartDate instead of startdate_str

I just verified at my end and the outbound works as expected. After installing the hotfix, have you restarted your server?

Hi Praneeth ,
We recycled the servers. This is what we are doing. we set the response property in data transform.
I set Property Startdate_str in data transform. I have mapped pzExternalName value to StartDate in Startdate_str property. we generate JSON response using function responseObjPage .getJSON( false );
I'm expecting JSON response to contain tag StartDate instead of StartDate_str. please let me know if i'm missing something.
Thanks

If you are using property qualifiers, you are not supposed to generate JSON using the clipboard API getJSON(). You should instead have Map From as JSON on the response tab of your service REST rule and Map From Key should be the embedded page property whose JSON representation you need.

HI Praneeth ,
is there any way to use getJSON() API and acheive this functionality? we use a common activity which gets the response page as parameter and generate the response for all the services so we will not be able to use Map from JSON.

Thanks praneeth. I think we cannot use this function then. is it possible to tell me the class the MAP from JSON uses to generate the JSON ? may be i'll try to write some java code around the class and see if it works.

The method used by Map from JSON is tools.getServiceUtils().mapOutboundData(). You could see its usage in step 5 of Rule-Connect-REST.Invoke activity.
