<fmt:bundle> tag is used to avail the resource for using the formats. A resource bundle is loaded by this tag which will be used by its tag body.
Attributes of <fmt:bundle>
- basename : This is a required attribute used for specifying the resource bundle base name. 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.
- prefix : This is an optional attribute that may be used for adding to the beginning to the value of the key of <fmt:message> action. for example <fmt:message key=”user.name”/>. Here user is a prefix.
An example is being given here will demonstrate you how to use the <fmt:bundle> 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:bundle> tag to load the bundle resource from the resource variable. So as an output you will see the values written in English language.
