In the Java platform, java.util.Locale
(http://docs.oracle.com/javase/7/docs/api/java/util/Locale.html
)
represents a specific geographical, political, or cultural region. The
string representation of a locale consists of the international standard
two-character abbreviation for language and country and an optional
variant, all separated by underscore (_
) characters. Examples of
locale strings include fr
(French), de_CH
(Swiss German), and
en_US_POSIX
(English on a POSIX-compliant platform).
Locale-sensitive data is stored in a java.util.ResourceBundle
(http://docs.oracle.com/javase/7/docs/api/java/util/ResourceBundle.html
).
A resource bundle contains key-value pairs, where the keys uniquely
identify a locale-specific object in the bundle. A resource bundle can
be backed by a text file (properties resource bundle) or a class (list
resource bundle) containing the pairs. You construct a resource bundle
instance by appending a locale string representation to a base name.
The Duke’s Bookstore application (see
Chapter 60, "Duke’s Bookstore Case Study
Example") contains resource bundles with the base name
messages.properties
for the locales de
(German), es
(Spanish), and
fr
(French). The default locale, en
(English), which is specified in
the faces-config.xml
file, uses the resource bundle with the base
name, messages.properties
.
