JasperReports：获取JRRuntimeException：创建SAX解析器时出错
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构建应用程序。 以下是pom.xml中的JasperReports依赖项
net.sf.jasperreports jasperreports 4.5.1 jasperreports-javaflow jasperreports-javaflow 4.5.1 以下是生成报告的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;
当我调用此代码时，它会给我以下错误：

- 我们使用iReport和JasperReports版本作为4.5.1
- 我已将XercesImpl.jar （版本2.8.1）依赖项放在类路径中
- 我们正在使用Jdk.1.6.0_33
请帮助如何删除此错误？
正如您从stacktrace的这一行所看到的：
org.apache.crimson.parser.XMLReaderImpl.setProperty(XMLReaderImpl.java:266)
Crimson XML解析器用于您的应用程序。
Crimson实现不支持与这些值不同的属性值[1] ：
"http://xml.org/sax/properties/lexical-handler"
和
"http://xml.org/sax/properties/declaration-handler"
但JasperReports引擎尝试使用http://java.sun.com/xml/jaxp/properties/schemaLanguage属性（正如您从stacktrace [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中。
备注 ：
[1]：在org.apache.crimson.parser.XMLReaderImpl类中查看方法getProperty(String)的源代码 。
[2]： JR引擎尝试在net.sf.jasperreports.engine.xml.BaseSaxParserFactory.configureParser(SAXParser)方法中为SAXParser设置此属性 。
