How to add a json array to a table using java so that I can pass cookies?

I have json object like this

{
  "data":[
    {
       "no":1,
       "name" : "yuda",
       "address" : "surabaya"
    },
    {
        "no":2,
        "name":"adi",
        "address":"jakarta"
    }
  ],
  "comp_name":"TEST CORP",
  "title":"Company employee",
  "status":"success"
}

I serve that json with http rest API and I want to create report with jasper report and I have success if I pass it as an url JsonQueryExecuterFactory.JSON_SOURCE.

My problem is that I can't include session cookie in JSON_SOURCE, the solution I'm trying is to create a http request in java code and then include it with JsonQueryExecuterFactory.JSON_INPUT_STREAM, but it's not working, it just shows blank page. Even though I update parameter from $P{net.sf.jasperreports.json.source} to $P{JSON_INPUT_STREAM} it doesn't work.

Petter Friberg :

This is a full example of loading your json from a http request via java (you can add headers as you like), using a subreport to pass the data node as a subDataSource

Example URL: http://www.jdd.it/so/jsonTest.json *Your json is available on this url

The key is to subDataSource the data node ((net.sf.jasperreports.engine.data.JsonDataSource)$P{REPORT_DATA_SOURCE}).subDataSource("data") and pass this to subreport

Nothing special in this report, the fields corresponds to the fields in your data node, remember to compile subreport to .jasper before running java code, since .jasper is indicated in main report.

Java code

//Get our main report
JasperReport report = JasperCompileManager.compileReport("jsonMain.jrxml");

//Open url connection
URLConnection urlConn = new URL("http://www.jdd.it/so/jsonTest.json").openConnection();
//set some cookies
urlConn.setRequestProperty("Cookie", "cookie1=hello; cookie2=world");

//Get the stream
try (InputStream is =urlConn.getInputStream()) {
    Map<String, Object> parametersMap = new HashMap<>();
    //Pass to parameter map
    parametersMap.put(JsonQueryExecuterFactory.JSON_INPUT_STREAM, is);
    //Fill report
    JasperPrint jasperPrint = JasperFillManager.fillReport(report, parametersMap);
    //Export to pdf
    JRPdfExporter exporter = new JRPdfExporter();
    exporter.setExporterInput(new SimpleExporterInput(jasperPrint));
    exporter.setExporterOutput(new SimpleOutputStreamExporterOutput("json.pdf"));
    SimplePdfExporterConfiguration configuration = new SimplePdfExporterConfiguration();
    configuration.setMetadataAuthor("Me");
    exporter.setConfiguration(configuration);
    exporter.exportReport();
}
