用的tomcat5 和myeclipse6.5 各种包都添加了。手动添加了spring.jar和 spring-struts.jar的包。
出现的错误如下：
HTTP Status 404 - /add--------------------------------------------------------------------------------type Status reportmessage /adddescription The requested resource (/add) is not available.
--------------------------------------------------------------------------------Apache Tomcat/5.5.23菜鸟，没人指导。都是自己琢磨，请大家指教
