The text tag is a generic tag that is used to render a I18n text message. Follow one of the three steps:
- The message must be in a resource bundle with the same name as the action that it is associated with. In practice this means that you should create a properties file in the same package as your Java class with the same name as your class, but with .properties extension.
- If the named message is not found, then the body of the tag will be used as default message.
- If no body is used, then the name of the message will be used.
Let us check the following example to understand the usage of text tag:
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; private String name; public String execute() { return SUCCESS; } public String getName() { return name; } public void setName(String name) { this.name = name; } }
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>Text Data Tag Struts2 | dineshonjava.com</title> </head> <body> <h1><span style="background-color: #FFFFcc">Text Data Tags Example!</span></h1> <b><s:i18n name="HelloWorldAction"> <s:text name="name.success"/><br> <s:text name="name.xyz">Message doesn't exists</s:text><br> <s:text name="name.msg.param"> <s:param >DINESH</s:param> </s:text> </s:i18n></b> </body> </html>
Configuration Files
Let us create a property file with the same name as of your action class package name. So in this case we will create myapp.properties file and keep in the class path:
label.username = User Name label.submit = Submit name.success = This is success message name.msg.param = The param example - param : {0}
struts.xml
<?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="texttag" class="com.dineshonjava.struts2.action.DataTagAction"> <result name="success">/success.jsp</result> </action> </package> </struts>
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/texttag.
This will give you following screen:
