Struts 2 - The Date Tag
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 produce the following screen −
