It seems your code can not find the class: Caused by: java.lang.ClassNotFoundException: org.apache.xerces.dom.ElementNSImpl
看来你的代码找不到类：引起：java.lang.ClassNotFoundException：org.apache.xerces.dom.ElementNSImpl
from ODF Toolkit
来自ODF 工具包
Note: ODFDOM requires Apache Xerces. The jar file xercesImpl.jar also must exist in a folder lib next to odfxsltrunner.jar file, or it must be in the classpath. The ODF XSLT Runner NetBeans projects includes a reference to xersesImpl.jar in the runtime classpath which has to be adapted after checking out the project.
注意：ODFDOM 需要 Apache Xerces。jar 文件 xercesImpl.jar 还必须位于 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，在签出项目后必须对其进行调整。
