The tag is used to store the given locale in the locale configuration variable.AttributeThe tag has the following attributes −AttributeDescriptionRequiredDefaultValueSpecifies a two-part code that represents the ISO-639 language code and an ISO-3166 country code.Yesen_USvariantBrowser-specific variantNoNonescopeScope of the locale configuration variableNoPageExampleResource bundles contain locale-specific objects. Resource bundles contain key/value pairs. When your program needs a locale-specific resource, you keep all the keys common to all the locale but you can have translated values specific to locale. Resource bundles helps in providing content specific to locale.A Java resource bundle file contains a series of key-to-string mappings. The method that we ... Read More

The tag will make the specified bundle available to all tags that occur between the bounding and tags. With this, you need not specify the resource bundle for each of your tags.For example, the following two blocks will produce the same output − AttributeThe tag has the following attributes −AttributeDescriptionRequiredDefaultbasenameSpecifies the base name of the resource bundle that is to be loaded.YesNonePrefixValue to prepend to each key name in subtagsNoNoneExampleResource bundles contain locale-specific objects.
