上面虽然有错误，但tomcat还能起来，然后我跑http://localhost:8080/myproject/ 就报错了

説明 The server encountered an internal error () that prevented it from fulfilling this request.

例外

javax.servlet.ServletException: ActionMappings 或者 ActionFormBeans collection找不到
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:825)
org.apache.jasper.runtime.PageContextImpl.handlePageException(PageContextImpl.java:758)

org.apache.jasper.servlet.JspServlet.service(JspServlet.java:236)

原因

Digester是解析xml文件的包
是你的某个xml格式错误吧
你用到了struts的validation框架,看看他的配置文件是不是写错了

工程的属性，java build path里libraries下已经添加了所有WEB-INF\lib\里的包了，包括servlet.jar。。。
不在eclipse里起tomcat,直接在外面起tomcat,一样的情况

上文中提到：servlet.jar) - jar not loaded.
应该是servlet.jar这个包没有加载吧，你在eclipse3.1的环境配置里看一下，应该可以手动配置加载的
