I just tried that and now got a weird exception. Here's my code: String input=FacesContext.getCurrentInstance().getExternalContext().getRealPath("/REPORT.jrxml"); File reporte= new File(input); design = JRXmlLoader.load(reporte); report = JasperCompileManager.compileReport(design); Listprints=new ArrayList(); for (int i=folioInicial;i<=folioFinal;i++) { parametros.put("p_oficio",i); print= JasperFillManager.fillReport(report, parametros, new JREmptyDataSource()); prints.add(print); } JRPdfExporter pdfExporter = new JRPdfExporter (); pdfExporter.setParameter (JRExporterParameter.JASPER_PRINT_LIST, prints); pdfExporter.setParameter (JRExporterParameter.OUTPUT_FILE,new File("REPORT.pdf")); pdfExporter.exportReport(); The exception is: SEVERE: net.sf.jasperreports.engine.JRException: Image read failed. at net.sf.jasperreports.engine.util.JRJdk14ImageReader.readImage(JRJdk14ImageReader.java:73) at net.sf.jasperreports.engine.util.JRImageLoader.loadAwtImageFromBytes(JRImageLoader.java:167) at net.sf.jasperreports.engine.JRImageRenderer.getImage(JRImageRenderer.java:407) at net.sf.jasperreports.engine.JRImageRenderer.getOnErrorRendererForImage(JRImageRenderer.java:310) at net.sf.jasperreports.engine.export.JRPdfExporter.exportImage(JRPdfExporter.java:1381) at net.sf.jasperreports.engine.export.JRPdfExporter.exportElements(JRPdfExporter.java:854) at net.sf.jasperreports.engine.export.JRPdfExporter.exportPage(JRPdfExporter.java:818) at net.sf.jasperreports.engine.export.JRPdfExporter.exportReportToStream(JRPdfExporter.java:695) at net.sf.jasperreports.engine.export.JRPdfExporter.exportReport(JRPdfExporter.java:417)

I'd like to know If it's possible to generate a report template multiple times and have the resulting templates concatenated in a single PDF file. As of now, this os how i generate a single report: String input=FacesContext.getCurrentInstance().getExternalContext().getRealPath("/REPORT.jrxml"); File reporte= new File(input); design = JRXmlLoader.load(reporte); report = JasperCompileManager.compileReport(design); parametros.put("p_id",1); print= JasperFillManager.fillReport(report, parametros, new JREmptyDataSource()); byte[]archivo=JasperExportManager.exportReportToPdf(print); InputStream stream=new ByteArrayInputStream(archivo); content= new DefaultStreamedContent(stream, "application/pdf","REPORT"); The "p_id" parameter is what would change in every iteration of the report but the template would be the same. All the reports would be printed in the same file. How can i achieve this?

Hi, I'm a JasperReport noob and I'm trying to build a simple report with some nodes that can repeat multiple times. Here's my xml: <?xml version="1.0" encoding="UTF-8" standalone="yes"?> <Comprobante xmlns="http://www.sat.gob.mx/cfd/2" version="2.0" serie="FAC-AA" folio="1" fecha="2010-12-25T09:39:21.044-06:00" sello="um8oh1kJZ5IYyJrbefc5XYiah8e2bf3hFuhlcFFezlkdu1iQWfVsmWZvJC/RMvNyUM5/Wh5M0daT 3KDlC8g6z6AtWnrEgh75LufjlMu5F1OimTP6TDc3gE3xpiT66RVVAen86kRx5FW62p34+7Xbh+H6 3mYdWf6YU6dkWbKClkA=" noAprobacion="2010" anoAprobacion="2010" formaDePago="Pago en una sola exhibición" noCertificado="30001000000100000800" subTotal="1900.49" descuento="665.1715" total="1531.20" metodoDePago="Efectivo" tipoDeComprobante="ingreso"> <Emisor rfc="AAAA000000XX1" nombre="Razon social"> <DomicilioFiscal calle="Calle" noExterior="00" noInterior="00" colonia="Colonia" localidad="localidad" municipio="municipio" estado="estado" pais="México" codigoPostal="03330"/> </Emisor> <Receptor rfc="BESR870619RD7" nombre="Roberto Betancourt"> <Domicilio calle="Priv.

I'm following the tutorial posted at: http://jasperforge.org/website/ireportwebsite/IR%20Website/ir_xml_datasources.html?header=project&target=ireport But I'm having a lot of issues when trying to define subdatasources. My Xpath for the subdatasource is /Comprobante/Conceptos/Concepto and the datasource expression for the list is: $P{REPORT_DATA_SOURCE}.subDataSource("/Comprobante/Conceptos/Concepto") In this way, the first Concepto node is repeated three times instead of displaying three different Concepto nodes. I've also tried setting /Conceptos/Concepto and the Xpath and the datasource expression but nothing appears. Is it a bug or am i making some stupid noob mistake?
