我们正在尝试将我们的Tomcat版本从7.0.73升级到更新版本。在任何更高版本上，除了我们的“DBPrism Servlet引擎”之外，一切运行正常。它部署时没有任何问题，但在运行测试时，它会在C-Prompt中抛出以下异常：

我看过不同网站的多个帖子都无济于事， 任何帮助将不胜感激

关闭Tomcat服务器。 使用文本编辑器打开catalina.properties文件。它通常位于/ install-path-to-tomcat / conf /中。在继续操作之前，请为此文件创建一个副本。 在文件的最顶部添加以下属性：
javax.xml.parsers.DocumentBuilderFactory = com.sun.org.apache.xerces.internal.jaxp.DocumentBuilderFactoryImpl javax.xml.transform.TransformerFactory = com.sun.org.apache.xalan.internal.xsltc.trax.TransformerFactoryImpl javax.xml.parsers.SAXParserFactory = com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl javax.xml.datatype.DatatypeFactory = com.sun.org.apache.xerces.internal.jaxp.datatype.DatatypeFactoryImpl
不幸的是，我无法轻松地对Tomcat进行配置更改，我仍在寻找如何从我要部署的Web应用程序中修复此问题。
