We are trying to produce reports of an HTML format that contain sub reports, they work fine exporting to PDF using JasperExportManager.exportReportToPdfFile (jasperPrint, fullFileName)But don’t include the sub reports when using the API: JasperExportManager.exportReportToHtmlFile (jasperPrint, fullFileName);I.e. sub reports are not generated on HTML page. We also tried. JRHtmlSaveContributor jr = new JRHtmlSaveContributor(); jr.save(jasperPrint, new File(fullFileName));Can someone help please.
