Create action classes:
package com.dineshonjava.struts2.action; import com.opensymphony.xwork2.ActionSupport; /** * @author Dinesh Rajput * */ public class DataTagAction extends ActionSupport { private static final long serialVersionUID = -7744420104547018874L; public String execute() { return SUCCESS; } }
Create Bean class:
UserBean.java
package com.dineshonjava.struts2.bean; /** * @author Dinesh Rajput * */ public class UserBean { private String userName = "Dinesh Rajput"; private String userAge = "27"; private String userPhone = "9876543210"; private String userAddress = "Noida"; public String getUserName() { return userName; } public void setUserName(String userName) { this.userName = userName; } public String getUserAge() { return userAge; } public void setUserAge(String userAge) { this.userAge = userAge; } public String getUserPhone() { return userPhone; } public void setUserPhone(String userPhone) { this.userPhone = userPhone; } public String getUserAddress() { return userAddress; } public void setUserAddress(String userAddress) { this.userAddress = userAddress; } }
Create views
Let us have success.jsp with the following content:
<%@ page contentType="text/html; charset=UTF-8"%> <%@ taglib prefix="s" uri="/struts-tags"%> <html> <head> <STYLE type="text/css"> b{color: blue;} </STYLE> <title>Push Data Tag Struts2 | dineshonjava.com</title> </head> <body> <h1><span style="background-color: #FFFFcc">Property Data Tags Example!</span></h1> <hr/><b>Simple </b><br/><br/> <s:bean name="com.dineshonjava.struts2.bean.UserBean" var="userBean"> Name : <s:property value="#userBean.userName"/><br/> Age : <s:property value="#userBean.userAge"/><br/> Phone : <s:property value="#userBean.userPhone"/><br/> Address : <s:property value="#userBean.userAddress"/> </s:bean> <hr/><b>Using push tag to display</b><br/><br/> <s:push value="#userBean"> Name : <s:property value="userName"/><br/> Age : <s:property value="userAge"/><br/> Phone : <s:property value="userPhone"/><br/> Address : <s:property value="userAddress"/> </s:push> </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.enable.DynamicMethodInvocation" value="false" /> <constant name="struts.devMode" value="false" /> <constant name="struts.custom.i18n.resources" value="myapp" /> <package name="default" extends="struts-default" namespace="/"> <action name="pushtag" class="com.dineshonjava.struts2.action.DataTagAction"> <result name="success">/success.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>Struts2DataTag</display-name> <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> <welcome-file-list> <welcome-file>index.jsp</welcome-file> </welcome-file-list> </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/doj/pushtag.
This will give you following screen:
