代码
File reportFile = new File("C:/Documents and Settings...../report1.jrxml");
JasperDesign jasperDesign = JRXmlLoader.load(reportFile);
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, null, conn);
JasperViewer jv = new JasperViewer(jasperPrint);
但我能够生成其他类型的报告文件。这个excell文件正在生成，但数据不在文件中。我使用 jasperreports.jar 文件。这是由于弃用我想。我怎么解决这个问题？
