nils.stritzel Posted February 26, 2021 Share Posted February 26, 2021 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,

nils.stritzel Posted March 1, 2021 Author Share Posted March 1, 2021 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.
