如何在EclipseJuno中运行servlet？

当我试图执行servlet程序时，我遇到了以下错误。请帮助我如何解决此错误？ 我尝试了许多网站，但我无法清除错误。我想我在设置环境变量时做错了。我已经安装了jdk1.7.0_45和ApacheTomcat7.0.47

您发布的内容是服务器启动期间通常的控制台显示。张贴您的错误跟踪。另外，您使用eclispe多久了

我收到HTTP状态404-/yt/type Status report message/yt/description请求的资源不可用。Apache Tomcat/7.0.47确保遵循了正确的eclipse文件层次结构。Java Resources->src->package->servlet您是否试图通过jsp页面运行servlet？你在你的jsp页面上导入了这个包吗？没有，我正在通过html页面运行servlet。在my web.xml中是这样的。很抱歉，我无法发布我的xml文件。您的错误与此类似[同一错误][1][1]：我引用了，但仍然无法清除。
