使用Apache ODF Toolkit获取java.lang.NoClassDefFoundError：org / apache / xerces / dom / ElementNSImpl

Question

我正在尝试使用ods阅读Apache ODF Toolkit文件。我在尝试使用以下代码加载电子表格时遇到java.lang.NoClassDefFoundError错误 -

SpreadsheetDocument data = SpreadsheetDocument.loadDocument(file);

以下是错误跟踪 -

看来您的代码无法找到该类： 引起：java.lang.ClassNotFoundException：org.apache.xerces.dom.ElementNSImpl

来自ODF Toolkit

注意：ODFDOM需要Apache Xerces。 jar文件xercesImpl.jar也必须存在于odfxsltrunner.jar文件旁边的文件夹lib中，或者它必须位于类路径中。 ODF XSLT Runner NetBeans项目在运行时类路径中包含对xersesImpl.jar的引用，在检出项目后必须对其进行调整。
