Hello,
I created a gp service that allows to load a csv file (It contains addresses and It is attached at this post).
It works as expected :
I get an Item ID.
I created a gp service that allows to geocode addresses (from the Item ID generated at the step previous) :
https://supad-t1-age1081.westus2.cloudapp.azure.com/server/rest/services/BatchGeocode3/GPServer
It works as expected :
In a Web Application, I use the Geoprocessor class to execute the task :

It works. The json output file is created on the server in \arcgisjobs\batchgeocode3_gpserver\<ID>\scratch:
However, I'm not able to get the result in the client-side (web app).
I think I must use waitForJobCompletion() method but I tried unsuccessfully.
Could you help me please ?
Thank you,
Bertrand
