Java 为什么我在尝试在TomCat上部署项目时（从NetBeans）会收到此错误消息？（上下文启动失败）

我不太喜欢Maven和NetBeans（我在 我有以下问题

我从中获得了一个使用Maven特性的项目，名为project 原型并选择教程中指定的原型（名为entando原型门户引导的原型，即生成entando门户的原型）

在下一个NetBeans窗口中，我将项目名称指定为myfirstportal和组id我指定了com.entando

我没有更改默认项目路径，即：

/home/andrea/NetBeansProjects/myfirstportal

然后，在NetBeans项目选项卡中，我选择我的项目，执行Maven清理和构建任务，该任务持续几秒钟，并以一条构建成功消息正确结束

看来构建过程还可以

然后我选择我的项目并执行Run，因此我选择我的TomCat安装

启动过程开始，但在结束时，我始终收到以下错误消息：

正如您在最后看到的，流程失败，并显示以下特定错误消息：

我错过了什么？我能做些什么来解决这个问题

我认为您的web.xml丢失或应用程序上下文格式不正确

打开“服务”窗口（如果未打开，请转到：窗口>服务） 右键单击Tomcat服务器并选择查看服务器日志。 现在您可以看到导致Tomcat不部署war的实际异常
