Question

我正在开发一个使用Jasper报告来显示一些报告的java Web应用程序。现在我的依赖性版本发生了一些变化，我收到了以下错误：

net.sf.jasperreports.engine.JRRuntimeException: java.io.IOException: SAX2 driver class org.apache.xerces.parsers.SAXParser not found
at net.sf.jasperreports.renderers.BatikRenderer.ensureSvg(BatikRenderer.java:229)

at net.sf.jasperreports.engine.export.JRPdfExporter.exportReportToStream(JRPdfExporter.java:695)
at net.sf.jasperreports.engine.export.JRPdfExporter.exportReport(JRPdfExporter.java:396)
at net.sf.jasperreports.engine.JasperExportManager.exportToPdfStream(JasperExportManager.java:191)
at net.sf.jasperreports.engine.JasperExportManager.exportReportToPdfStream(JasperExportManager.java:527)

我认为错误可能来自构建路径。这是我的依赖树：

你能否就这个错误给我一些建议？

Answer 1

这肯定与xerces地狱有关......我看到你在类路径上有xercesImpl.jar有这个类，但是你还有其他库包括这个类xmlParserAPIs.jar，尝试删除其中一个我将删除xercesImpl.jar。

看看这个...... Dealing with "Xerces hell" in Java/Maven?

Answer 2

SAX2驱动程序类org.apache.xerces.parsers.SAXParser位于xerces-2.9.0.jar文件中。

在您启动网络应用程序时检查它是否在您的类路径中，如果不存在，只需添加它。

同时检查您所包含的某些依赖项是否必须声明为provided，这意味着它们已经存在于您的应用程序服务器lib文件夹中，因为可能存在版本冲突。

找不到SAX2驱动程序类
