index.jsp必须直接放在webroot目录下你的这个配置是默认放在根目录下的
<welcome-file>index.jsp</welcome-file>
控制台没报错，url地址栏你也确定没写错？在myeclipse中，对着你的项目点右键，选择properties，然后在收索烂输入web，在点web，看看那web Context-root是不是你输入的url地址烂，如果是，那我觉得就是你没发布到tomcat中
应该发布了，tomcat文件夹路径：E:\Program Files\Tomcat 6.0\webapps\Courses
在Courses文件夹里有这个项目的文件及文件夹。
那你的url就是http://localhost:8080/Courses大写
