struts与hibernate整合时出现一个问题，百思不得其解

register.jsp中代码<%@ page language="java" import="java.util.*" pageEncoding="ISO-8859-1"%>

String path = request.getContextPath();
String basePath = request.getScheme() + "://"

public String save() throws Exception
{
Person person = new Person(); person.setUsername(username); person.setPassword(password); person.setAge(age); java.sql.Date registerDate = new java.sql.Date(new java.util.Date()
.getTime());
person.setRegisterdate(registerDate); DBPerson.save(person);

List<Person> list=DBPerson.listAll();

HttpServletRequest requeset=ServletActionContext.getRequest();

requeset.setAttribute("list", list);

return "success";

}
}进入register.jsp点submit按钮后会出现提示“The requested resource(/hibernate/save.action)is not available”;只用struts时就能够正常调用action，转到result的页面。我是跟着视频教学一起做的，虽然myeclipse版本和struts版本不同，应该不是这个问题吧求各位高手指点
