How to use JSON/REST datasource in Input Control

[simo.tuokko]

Hi,

We are trying to create report against REST API which returns data in JSON format (ElasticSearch).

We have managed to get report itself working in JasperSoft Studio Pro 7.9.0 using JSON Datasource.

In JasperReport Server 7.9.0 we were unable to give required parameters for JSON Datasource so we ended up importing datasource from Studio to Server as xml. See https://community.jaspersoft.com/questions/1185171/same-parameters-json-datasource-jasper-reports-server-jaspersoft-studio

Next step would be to add Input Control (multivalue) which would be populated from the same REST-datasource. When creating Input Control in Server's UI it seems that Server does not understand that imported datasource.xml is a datasource (as it is not available in the list of datasources). And as described earlier creating the JSON-datasource with needed parameters/options in Server is not supported. 

 

So does anyone know how to use JSON/REST datasource in Input Control or some other approach for this?
