  1. Solved it myself using <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JsonDataSource( new java.io.ByteArrayInputStream( $P{jsonData}.getBytes("UTF-8") ), "labelData")]]></dataSourceExpression> And subreportParameter jsonData is not needed.
  2. Hi, I want to show the following some json data in Jasper Report. The json could come from file or an URL, therefore I want to be totally flexible on this point. I did not see the possibility to pass the whole URL into DATA Adapter, simply setting the net.sf.jasperreports.http.data.url parameter in the report did not seem to have any effect. I came across the hint to put in a subreport, but that did not work for me either. I came up with code below, but seemingly passing in the stream has no effect. I tried with <subreportParameter name="REPORT_DATA_SOURCE"> <subreportParameterExpression><![CDATA[new net.sf.jasperreports.engine.data.JsonDataSource( new java.io.ByteArrayInputStream( $P{jsonData}.getBytes("UTF-8") ), ".")]]></subreportParameterExpression> </subreportParameter>[/code]and with <dataSourceExpression><![CDATA[new net.sf.jasperreports.engine.data.JsonDataSource( new java.io.ByteArrayInputStream( $P{jsonData}.getBytes("UTF-8") ), ".")]]></dataSourceExpression>[/code]but to no avail. json: { "labelData": [ { "batchNo": "9888", "boxNo": 1, "barcodeNo": "BB9B1399C2595DABE0530101007FAA1F", "noOfCards": 1000 }, { "batchNo": "9888", "boxNo": 10, "barcodeNo": "BB9B1399CA295DABE0530101007FAA1F", "noOfCards": 999 }, { "batchNo": "9888", "boxNo": 2,
