JasperReports：获取JRRuntimeException：创建SAX解析器时出错

Question

我们已经使用 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 __

<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>

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，它将给我以下错误：

1. 我们同时使用 iReport 和 JasperReports 版本4.5.1
2. 我已经将 XercesImpl.jar （版本2.8.1）依赖项放在类路径中
3. 我们正在使用 Jdk.1.6.0_33

请帮助我如何删除此错误？

Answer 1

从堆栈跟踪的这一行可以看到：

org.apache.crimson.parser.XMLReaderImpl.setProperty(XMLReaderImpl.java:266)

在您的应用程序中使用了 Crimson XML 解析器。

在 深红 实现不支持由这些值的属性值不同的[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（如从stacktrace
[2]所见）。

在 iReport的 使用 Xerces的 XML 解析器实现。例如，
iReport 4.7.0 和 iReport 5.2.0 使用的是 Xerces 的 2.8.0 版本。 __

您可以尝试将此（ Xerces ）库作为依赖项添加到 pom.xml 中。

注意事项 ：

[1]：参见方法的源代码getProperty(String)中 org.apache.crimson.parser.XMLReaderImpl
类。

[2]： JR 引擎尝试在method中为 SAXParser 设置此属性
net.sf.jasperreports.engine.xml.BaseSaxParserFactory.configureParser(SAXParser)
。
