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}

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:
