Struts 2 - The date tag

Advertisements


The date tag allows to format a Date in a quick and easy way. User can specify a custom format (eg. "dd/MM/yyyy hh:mm"), can generate easy readable notations (like "in 2 hours, 14 minutes"), or can just fall back on a predefined format with key 'struts.date.format' in the properties file.

Create action class:

package com.tutorialspoint.struts2;

import java.util.*;

public class HelloWorldAction{
   private Date currentDate;
   
   public String execute() throws Exception{
      setCurrentDate(new Date());
      return "success";
   }
   public void setCurrentDate(Date date){
      this.currentDate = date;
   }
   public Date getCurrentDate(){
      return currentDate;
   }
}

Create views

Let us have HelloWorld.jsp with the following content:

<%@ page contentType="text/html; charset=UTF-8" %>
<%@ taglib prefix="s" uri="/struts-tags" %>
<html>
<head>
<title>Hello World</title>
</head>
<body>
<h2>Current Date</h2>

<h3>Day/Month/Year Format</h3>
<s:date name="currentDate" format="dd/MM/yyyy" />

<h3>Month/Day/Year Format</h3>
<s:date name="currentDate" format="MM/dd/yyyy" />
	
</body>
</html>

Configuration Files

Your struts.xml should look like:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
   "-//Apache Software Foundation//DTD Struts Configuration 2.0//EN"
   "http://struts.apache.org/dtds/struts-2.0.dtd">
<struts>
<constant name="struts.devMode" value="true" />
   <package name="helloworld" extends="struts-default">

   <action name="hello" 
      class="com.tutorialspoint.struts2.HelloWorldAction" 
      method="execute">
      <result name="success">/HelloWorld.jsp</result>
   </action>

   </package>
</struts>

Your web.xml should look like:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
   xmlns="http://java.sun.com/xml/ns/javaee" 
   xmlns:web="http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd"
   xsi:schemaLocation="http://java.sun.com/xml/ns/javaee 
   http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd"
   id="WebApp_ID" version="3.0">
   
   <display-name>Struts 2</display-name>
   <welcome-file-list>
      <welcome-file>index.jsp</welcome-file>
   </welcome-file-list>
   <filter>
      <filter-name>struts2</filter-name>
      <filter-class>
         org.apache.struts2.dispatcher.FilterDispatcher
      </filter-class>
   </filter>

   <filter-mapping>
      <filter-name>struts2</filter-name>
      <url-pattern>/*</url-pattern>
   </filter-mapping>
</web-app>

Right click on the project name and click Export > WAR File to create a War file. Then deploy this WAR in the Tomcat's webapps directory. Finally, start Tomcat server and try to access URL http://localhost:8080/HelloWorldStruts2/hello.action. This will give you following screen:
