無法在Tomcat 7.0.69應用程序中部署War文件

Question

我需要將使用Java 1.5和Tomcat 5.5構建的現有項目遷移到使用Tomcat服務器7.0.69的Java 1.8。

每當我嘗試在Tomcat 7.0.69應用程序中部署我的war文件時，都會遇到以下異常

我正在使用Java 1.8來構建此應用程序。

這里是來自“ catalina.log”的錯誤：

我最近有同樣的問題。 我通過從項目的web.xml文件中刪除以下內容來解決此問題。

<login-config>
    <realm-name>Device-Monitor</realm-name>
</login-config>
