package com.yulin.struts;

import java.util.Date;

import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import org.apache.struts.action.Action;
import org.apache.struts.action.ActionForm;
import org.apache.struts.action.ActionForward;
import org.apache.struts.action.ActionMapping;

public class TiglibAction extends Action {

@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
    HttpServletRequest request, HttpServletResponse response)
    throws Exception {
   //输出普通字符串
   request.setAttribute("string", "输出普通string");
   //输出html文件
   request.setAttribute("html", "<font color='red'>输出html文件</font>");
   //输出date
   request.setAttribute("date", new Date());
   //输出number
   request.setAttribute("number", 12345.67);
   //输出User
   Group g = new Group();
   g.setName("China");
   User u = new User();
   u.setUsername("LinZhang");
   u.setAge(23);
   u.setGroup(g);
   request.setAttribute("user", u);

   return mapping.findForward("success");
}

}
public void setUsername(String username) {
   this.username = username;
}
public int getAge() {
   return age;
}
public void setAge(int age) {
   this.age = age;
}
public Group getGroup() {
   return group;
}
public void setGroup(Group group) {
   this.group = group;
}
}

package com.yulin.struts;

public class Group {
private String name;

public String getName() {
   return name;
}

public void setName(String name) {
