我已经使用这 2 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 web 应用程序时，我在浏览器中看不到它。我查看了已部署的文件夹，我的 webapp 就在那里。我什至在其中创建了一个 hello.jsp，当我尝试查看它时出现 404 HTTP 错误。
这是我配置为使用 tomcat 的 Eclipse 的屏幕截图。它还显示了已部署的目录和我创建的 hello.jsp 文件。

这是我的浏览器无法看到 hello.jsp 的屏幕截图。

我创建了另一个 hello.jsp 并将其放在 $TOMCAT_INSTALL_FOLDER/webapps/ROOT 中，我可以在浏览器上看到它。
有什么想法可能是错的吗？
谢谢
附言。这是我启动tomcat时的控制台eclipse输出。顶部某处有一个警告，但在 stackoverflow 中阅读了另一个讨论，据说我可以忽略它。
