Struts2 - Text Tag (Data Tags)

In this section, we are going to describe the text tag. The text tag is a generic tag that is used to render a I18n text message. Follow one of the three steps:

1. Keep the message to be displayed in a resource bundle with the same name as the action that it is associated with ie. create a properties file in the same package as your Java class with the same name as your class, but with .properties extension.

2. If the property file does-not work or the message is not found in the resource bundle, then the body of the tag will be used as default message.

3. If there is no body, then the name of the message will be used. Add the following code snippet into the struts.xml file.

struts.xml

<action name="textTag" class="net.struts2.textTag">
   <result>/pages/genericTags/textTag.jsp</result>
</action>

Create an action class as shown below:

textTag.java

package net.struts2;
import com.opensymphony.xwork2.ActionSupport;

public class textTag extends ActionSupport {

  public String execute() throws Exception{
  return SUCCESS;
  }
}

Create a property file in the same package where your Java program file (textTag.java) is saved with the name as package.properties.

package.properties

webname1 = http://www.struts2.net
webname2 = http://www.java.com
webname3 = http://www.newstrack.com

Now create a jsp page to see the working of the text tags.
The first three tags , and uses the package.properties file to display the text message.
The next tag Vinod, Amit, Sushil, ....... uses the body of the tag as a default message.
The last tag does not have access to the package.properties files nor does it have a body so it uses name of the message to display.


textTag.jsp


<%@ taglib prefix="s" uri="/struts-tags" %>

  <head>
  <title>Text Tag (Data Tag) Example!</title>

  <body>

  <s:text name="webname2"></s:text><br>
  <s:text name="webname3"></s:text><br>
  <s:text name="empname">Vinod, Amit, Sushil, .......</s:text><br>
  <s:text name="empname"></s:text>

  </body>
</html>
