java - Tomcat登录在FormAuthenticator中重定向NullPointerException

Question

我在部署到我公司的 tomcat 服务器上的 Web 应用程序时遇到了困难。我可以将其部署到我自己的测试服务器并正常访问，但是当我将其部署到测试服务器并访问该应用程序时，它显示一个空白页面并记录以下错误:

Apr 26, 2013 12:22:42 PM org.apache.catalina.connector.CoyoteAdapter service

我已经为此花费了几个小时。我将衷心感谢您的帮助!谢谢! :)

我找到了一个半合理的解决方法，即在 netbeans 而不是 IntelliJ 中构建项目。可能与项目的结构有关，但我现在没有时间担心。
