I've got a question about nested JSON/Multiple querries.
I currently have a report using WebserviceQuerry that returns me a JSON. To get everything I need, I use a subreport, this passes to a subreport etc etc.
I'm wondering if this can be made more efficiënt?
I can access hostid and name as I've set "result" as root path. But how can I access all the information under "items"?
Jasperreports 6.3.1 supports JSONQL, can this somehow be used to access those fields?
Should I go about it some other way?
You should be able to achieve what you want with either JSON or JSONQL query languages. JSONQL has more features and is meant to replace JSON.
Your case looks similar to the ones described in the documentation for JSONQL datasource:
You can also grab the sample files from the github project: https://github.com/Jaspersoft/jasperreports/tree/jr-6-3-1/jasperreports/...
