本文介绍了将Java Struts项目部署到Tomcat服务器的过程，包括将JavaStrutsDemo部署到tomcat webapps目录。详细阐述了登录流程，从index.jsp页面提交用户名和密码，经struts.xml配置，由LoginAction执行验证，根据结果跳转到相应页面，还给出了相关配置文件和代码。
启动服务器：
tomcat的webapps下可以部署创建的web project：
创建好的JavaStrutsDemo部署到tomcat webapps目录下
1、http://127.0.0.1:8080/JavaStrutsDemo/index.jsp
2、index.jsp - post username password action login
3、struts.xml - struts action login
4、cgh.StrutsAction.LoginAction 执行 execute
5、根据执行返回值，success或者login 比较struts.xml中的配置跳转到index.jsp或者welcom.jsp
