我的问题是：我无法从java编译我的报告。 好吧，我在iReport中创建我的页面，然后从我的java代码中加载它。
这是我的一些错误：

这是我的java代码：
String url = "jdbc:oracle:thin:@localhost:1521:gpsi";
String user = "gestion";
String passwd = "password";
Connection conn = null;
String reference = this.commande_reference.getText();
try {

conn = DriverManager.getConnection(url, user, passwd);
Statement stmt = conn.createStatement();
JasperDesign jasperDesign = JRXmlLoader.load("./lib/report.jrxml");
JasperReport jasperReport = JasperCompileManager.compileReport(jasperDesign);
Map parameters = new HashMap();
parameters.put("ref",reference);
JasperPrint jasperPrint = JasperFillManager.fillReport(jasperReport, parameters, conn);
net.sf.jasperreports.view.JasperViewer.viewReport(jasperPrint,false);

不要同时使用DTD和XML架构，而是单独坚持使用DTD。换句话说，不要在JRXML文件中包含以下行：
<!DOCTYPE jasperReport PUBLIC "//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">
<jasperReport xmlns="http://jasperreports.sourceforge.net/jasperreports" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports http://jasperreports.sourceforge.net/xsd/jasperreport.xsd" name="report2" language="groovy" pageWidth="595" pageHeight="842" columnWidth="555" leftMargin="20" rightMargin="20" topMargin="20" bottomMargin="20">
你应该改为：
<!DOCTYPE jasperReport PUBLIC "//JasperReports//DTD Report Design//EN" "http://jasperreports.sourceforge.net/dtds/jasperreport.dtd">
<jasperReport>
<强>更新
由于iReport 3.4.7用于生成JRXML文件，用于对抗JasperReports 1.2.1，很明显生成的JRXML文件无法正确验证。因此，修复方法是使用iReport和JasperReports的兼容版本。

我通过将jdk bin目录添加到环境变量中解决了该错误。希望这对某人有帮助。
