我们使用 iReport4.5.1 创建了报告。它在 iReport 中正常工作。
之后，我们将报告集成到我们的应用程序中。我们使用 maven 构建我们的应用程序。以下是 pom.xml
中的 JasperReports 依赖项<dependency>
<groupId>net.sf.jasperreports</groupId>
<artifactId>jasperreports</artifactId>
<version>4.5.1</version>
</dependency>
<dependency>
<groupId>jasperreports-javaflow</groupId>
<artifactId>jasperreports-javaflow</artifactId>
<version>4.5.1</version>
</dependency>
下面是生成报告的 Java 代码:
String jrxmlFilePath = getConfigBundle().getString("jasper.templates.jrxml.path");
String jasperFilePath = getConfigBundle().getString("jasper.templates.jasper.path");
JasperCompileManager.compileReportToFile(jrxmlFilePath, jasperFilePath);
File jasperFile = new File(jasperFilePath);
Connection conn = setUpDataSource();
HashMap jasperParameter = setUpJasperParameterForPackingList(truckId, rackId, jasperFile);
JasperPrint jprint = JasperFillManager.fillReport(jasperFilePath, jasperParameter, conn);
ByteArrayOutputStream reportOutputStream = new ByteArrayOutputStream();
JasperExportManager.exportReportToPdfStream(jprint, reportOutputStream);
return reportOutputStream;
当我调用这段代码时，它会给我以下错误:

- 我们同时使用 iReport 和 JasperReports 版本 4.5.1
- 我已将XercesImpl.jar(版本 2.8.1)依赖项放入类路径中
- 我们正在使用 Jdk.1.6.0_33
请帮助我如何消除这个错误？
最佳答案
从堆栈跟踪的这一行可以看出:
org.apache.crimson.parser.XMLReaderImpl.setProperty(XMLReaderImpl.java:266)
Crimson XML 解析器用于您的应用程序。
Crimson 实现不支持不同于这些值的属性值[1]:
"http://xml.org/sax/properties/lexical-handler"
和
"http://xml.org/sax/properties/declaration-handler"
但是 JasperReports 引擎尝试使用 http://java.sun.com/xml/jaxp/properties/schemaLanguage 属性(正如您从堆栈跟踪[2] 中看到的那样)。
iReport 正在使用 Xerces XML 解析器实现。例如，iReport 4.7.0 和 iReport 5.2.0 使用的是 2.8.0 版本的 Xerces .
您可以尝试将此 (Xerces) 库作为依赖项添加到 pom.xml。
注释:
[1]:见方法源码getProperty(String)在 org.apache.crimson.parser.XMLReaderImpl 类中。
[2]:JR 引擎尝试在 net.sf.jasperreports.engine.xml.BaseSaxParserFactory.configureParser(SAXParser) 中为 SAXParser 设置此属性 方法。
