java - Tomcat服务器升级后项目出现异常

Question

我们正在尝试将我们的 Tomcat 版本从 7.0.73 升级到更新的版本。在任何更高版本上，除了我们的“DBPrism Servlet 引擎”外，一切都运行良好。它部署没有任何问题，但是在运行测试时它在 C-Prompt 中抛出以下异常:

我已经查看了来自不同站点的多个帖子，但无济于事， 任何帮助将不胜感激

当前设置:带有最新 JDK 的 Windows 10 - 1.8_144

这里提出的解决方案对我有用:java.lang.SecurityException: org.xml.sax.SAXNotRecognizedException: Feature: http://apache.org/xml/features/allow-java-encodings

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。在继续之前制作此文件的副本。 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尝试部署的 Web 应用程序中修复此问题。
