我已经使用这两个指南来安装/配置eclipse和Tomcat。
http://wolfpaulus.com/jounal/mac/tomcat7
http://www.banym.de/eclipse/install-tomcat-with-eclipse
我可以通过Eclipse中的服务器选项卡启动Tomcat。但是当我尝试浏览我的webapp时，我无法在浏览器中看到它。我查看了部署的文件夹，我的webapp就在那里。我甚至在其中创建了一个hello.jsp，当我尝试查看它时，我收到了404 HTTP错误。
这是我配置为使用tomcat的Eclipse的屏幕截图。它还显示了我创建的已部署目录和hello.jsp文件。

这是我的浏览器无法看到hello.jsp的截图。

我创建了另一个hello.jsp并将其放在$ TOMCAT_INSTALL_FOLDER / webapps / ROOT中，我可以在浏览器中看到它。
任何想法可能出错？
由于
PS。这是我启动tomcat时的控制台eclipse输出。顶部有一个警告，但在stackoverflow中读取另一个讨论，据说我可以忽略它。
