Hi I'm having trouble with the speed of the report. My datasource is an XML using XPATH. IReport, the report is shown in less than 7 seconds and the java program it takes 8 minutes. This delay occurs in Fill. can anyone help? How do I get JRXmlDataSource.class? This would make any difference? Tks Luciano Code: public void fill() throws JRException, IOException { HashMap<String, Object> params = new HashMap<String, Object>(); System.out.println("InÃcio Fill: " + now()); ResourceBundle myresources = ResourceBundle.getBundle("report"); Document docXML = JRXmlUtils.parse(new File(sXMLDataSource)); params.put(JRXPathQueryExecuterFactory.PARAMETER_XML_DATA_DOCUMENT, docXML); params.put(JRXPathQueryExecuterFactory.XML_DATE_PATTERN, "yyyy-MM-dd"); params.put(JRXPathQueryExecuterFactory.XML_NUMBER_PATTERN, "#,##0.##"); params.put(JRXPathQueryExecuterFactory.XML_LOCALE, Locale.ENGLISH); params.put("REPORT_QUADRICULADO", sImprimeQuadriculado ); params.put("REPORT_FOLHAROSTO", sImprimeFolhaRosto ); params.put(JRParameter.REPORT_RESOURCE_BUNDLE, myresources ); //params.put(JRParameter.REPORT_LOCALE, Locale.US); System.out.println("Rodar2 Fill: " + now()); //JasperFillManager.fillReportToFile(sFileJasper, sFilePrint, params); oFilePrint = JasperFillManager.fillReport(sFileJasper, params); System.out.println("Fim Fill: " + now()); }
