【问题描述】：
我有一个在 tomcat 7 和 tomcat 6 中运行的 web 应用程序。但是当我尝试迁移到 tomcat 8 时它不会让我，有一些像这样的例外：

这是我的应用程序中的上下文文件：

我认为这与我的数据库连接有关，因为一旦我尝试做一些需要数据库连接的事情，它就会向我发送异常。
我正在使用 netbeans 8.2，在 Windows 7 中工作。我是使用 jsp 和其他东西的新手，所以我不知道我在这里缺少什么。有没有人有办法解决吗？或者你有我可以检查的tomcat 8的配置文件吗？非常感谢您的帮助。
谢谢？

我认为您正在将一个 jar 链接到您的 webapp，该 webapp 已经包含在 tomcat 中。你能列出你在
WEB-INF/lib中的所有罐子吗？
