Last Updated :
29 Dec, 2023
The <fmt:setBundle> tag in JSTL is used to set or load the resource bundle that is to be used in localization. This tag allows us to specify the bundle that contains the localized messages and enables the rendering of content in various languages that are specified by the user.
In this article, we will be discussing the Syntax along with the parameters of this tag. We will also see its additional attributes table and lastly the example demonstrating the actual implementation.

Java
package com.geeksforgeeks;
import java.util.ListResourceBundle;
public class GeeksBundle extends ListResourceBundle {
public Object[][] getContents() {
return contents;

Explanation of the above Program:
- In the above example, we have used the resource bundle as “GeeksBundle“
- Then we have used the <fmt:setBundle> tag to set the resource bundle and also store it in the variable names as “courses“
- We are displaying this course names using “${courses[‘course.java’]}, ${courses[‘course.python’]}, ${courses[‘course.algo’]}” in HTML using <p> tag
