JSTL fmt Tag setBundle Example <fmt:setBundle>

The <fmt:setBundle> tag is used to load a resource bundle and stores it in the named scoped variable or the bundle configuration variable.

<fmt:setBundle> tag in JSTL is used in a JSP page to set the resource bundle. A resource bundle is loaded by this tag and is stored into the named scoped variable or the bundle configuration variable.

Attributes of <fmt:setBundle>
  • basename : This is a required attribute used for specifying the base name of resource bundle . Basename is a resource name, follows the same component separator dot (.) as the package uses for specifying the fully qualified class name. It does not uses the any type of suffixes such as .properties, .class etc.
  • var : This is an optional attribute used for specifying the name of the exported base name to a variable.
  • scope : This is an optional attribute is used for specifying the scope of the variable.

An example is being given here will demonstrate you how to use the <fmt:setBundle> tag. In this example I have created a Properties file named myapp.properties that contains the key-value pair. Value of key are the English characters. Then created a JSP page named index.jsp into which I have set the locale using the <fmt:setLocale> tag. And then uses the <fmt:setBundle> tag to load the bundle resource from the resource variable. So as an output you will see the values written in English language.
