because no ResourceBundles will have been loaded by the time the determination is needed; therefore, they cannot be examined for their locality Also, it s possible that the JSF implementation may be localized for more languages than your application, and you don t want the application to display messages for any languages other than the ones you know your application supports

It is useful to understand the details of the algorithm for determining the correct locale based on the user s preferences sent by the browser Most browsers allow the user to configure a priority list of languages in which pages should be rendered Figure 14-2 illustrates this configuration in the Firefox Web browser These settings are sent to the server in the Accept-Language and Accept-Charset HTTP headers, which are exposed to the JSF runtime via the Servlet API During the Restore View phase of the request processing lifecycle, the calculateLocale( ) method is called on the ViewHandler, which causes the following algorithm to be performed and the result set as the locale property of the UIViewRoot for this view Note that if you need to provide a different algorithm for selecting the locale, it is very easy to do so using the custom ViewHandler techniques described in 13 For each language entry preferred sent in the Accept-Language header by the browser: 1 For each entry supported in the list of supported-locales from the faces-config xml file: a If preferred is exactly equal to supported, consider it a match and return b If the language portion of preferred is equal to the language portion of supported, and supported has no country defined, consider it a match and return 2 If no match is found in the supported-locales list: a If preferred is exactly equal to the default-locale, consider it a match and return b If the language portion of preferred is equal to the language portion of defaultlocale, and default-locale has no country defined, consider it a match and return If no match is found with the previous algorithm for any of the preferred languages sent in the Accept-Language header, and if there is a <default-locale>, use it Otherwise, just use LocalegetDefault( )

Let s work through some examples to clarify the algorithm Let s say the user prefers de_ ch, en, and fr as his or her language priorities, and the <locale-config> is as listed previously First, we consider de_ch It s not exactly equal to any of the supported-locales or the defaultlocale, so we continue on to en This doesn t match any of the supported-locales, but it does match the default-locale, so it is considered a match and the page is rendered in English Let s remove the default-locale from the locale-config and re-evaluate the algorithm Again, de_ch, has no match, so we continue The same goes for en We now come to fr There is an exact match in the supported-locale list, so the page is rendered in French The user can override the Locale determined by the previous algorithm either by calling setLocale( ) on the UIViewRoot directly, or by giving a locale attribute to the <f:view> tag, like in the following:

The locale attribute is ValueExpression-enabled, so the following is also valid:
<f:view locale="#{prefslocale}">
provided that the expression evaluates to a Locale instance or a string representation of a Locale instance as described earlier
PART III
How the Correct Character Encoding Is Determined
There is considerable confusion regarding meanings of the terms charset, character encoding, and character code Let s clear up some of that confusion before explaining how these terms relate to Web applications in general and Faces applications in particular The whole point of localization is to display your application so that it can be understood by users from specific geographic regions Since the Web is still mainly a textual medium, the elements that make up text are very important Let s say that the elements that make up text in a natural language are called characters A collection of characters grouped together in some logical fashion is called a character repertoire No specific computer representation or even sort order is implied by the concept of a character repertoire; it s purely a human concept A character repertoire is usually presented by giving the names of the characters and a visual representation of each one A character code is a big list of the characters in a character repertoire, with a non-negative integer number, known as a code position, assigned to each character Synonyms for code position are code point, code number, code element, and code set value With the introduction of the concept of character code comes the notion of the characters being sorted For example, Morse code lists each letter in the English alphabet in alphabetical order, followed by the numerals 0 through 9, followed by some control characters Finally, a character encoding is another big list, this time of the code positions in a character code with a sequence of binary numbers known as octets associated with each ASCII is probably the best known character encoding It is also a character code because each code position is also its encoding for example, the letter a is at code position 97, and it is also encoded as the number 97 Figure 14-3 illustrates the concepts of repertoire, code, and encoding Generally, the only concept you have to understand is character encoding The declaration of a character encoding is what allows the big sequence of bytes that comprise a Web page to be turned into meaningful localized human-readable text Without a character encoding, the browser would have no way to know how it should interpret the bytes for display The most common encoding for computer systems is, of course, ASCII, but this encoding doesn t travel well because it only contains characters for English The most common character encoding for the Web is called ISO-8859-1, also known as Latin 1 This encoding is a superset of ASCII, but also includes characters for Western and Northern European Languages
