Globalization Development Kit

• What is the GDK ?
• A toolkit that simplifies the development
  process, and reduces the cost of developing
  Internet applications that will be used to
  support a global environment
• The need for the GDK
• The complexity associated with the different
  globalization concepts, can make building and
  supporting a global Internet application quite a
  challenge for many companies.

4
Internet and Oracle Services

• Oracles Globalization Platform for J2EE
• Internet Services
• provides the development support for the J2EE
  middle tier to hide the complexity of
  synchronizing globalization operations across
  tiers
• Oracle Services
• provides development support in the middle tier
  to provide consistent globalization operations as
  provided in the database server

Developing a Global Internet Application

• Determining the user locale preference and
  synchronizing it with the application
• Specifying the character set for the input and
  output of web content
• Staging and managing translated content
• Getting consistent globalization operations
  between the application and the database

8
Supported Locale Sources
Locale Type Source HTTP language
preference Browser User Input Locale
Menu Locale preference from database Database LD
AP locale preference LDAP Application default
locale GDK
9
GDK Application configuration file

• Dictates the globalization behaviors and the
  properties of the application
• One application configuration file per J2EE
  application
• Alter the globalization behavior in the
  application, without the need to change the
  programs and to recompile them

10
Defining the locale sources and the application
locales

• Application configuration file gdkapp.xml
• ltlocale-sourcegt
• oracle.i18n.servlet.localeldap.LDAPInetOrgPers
  on
• lt/locale-sourcegt
• ltlocale-sourcegt
• oracle.i18n.servlet.localesource.HTTPAcceptLa
  nguage
• lt/locale-sourcegt
• ltapplication-localesgt
• ltlocalegtde-lt/localegt
• ltlocalegtjalt/localegt
• ltlocale default"yes"gten-USlt/localegt
• lt/application-localesgt

11
Detecting the Locale

• Locale loc request.getLocale( )
• Localizer localizer ServletHelper.getLocalizerIn
  stance(request) The GDK Localizer is an
  all-in-one globalization object that encapsulates
  comprehensive globalization attributes and methods

12
Character set for the input and output of web
content

• A single local character set dedicated to the
  whole application
• Use Unicode UTF-8 for all contents regardless of
  the language
• Use the native character set for each language

13
AUTO-CHARSET
14
Handling the character set

• Specify the Character set in the application
  configuration file.
• ltpage-charsetgtUTF-8lt/page-charsetgt
• ltpage-charsetgtAUTO-CHARSETlt/page-charsetgt
• ltlocale-charset-mapsgt
• ltlocale-charsetgt
• ltlocalegtjalt/localegtltcharsetgtEUC-JPlt/charsetgt
  
• lt/locale-charsetgt
• lt/locale-charset-mapsgt

15
Managing translated content

• Static Files HTML, GIF, XML etc.
• French version of index.html gt index_fr.html or
  fr/index.html
• ServletHelper.rewriteURL ( ) method rewrites a
  URL based on the rules specified in the
  application configuration file. ltimg
  src"ltServletHelper.rewriteURL("logo.jpg",requ
  est)gt"gt

16
Managing translated content

• Strings in the JSP / JAVA Servlets
• Externalized into Java ResourceBundle
• REPLACElt Locale user_localerequest.getLocale(
  )
• ResourceBundle
• rbResourceBundle.getBundle("resource",user_locale
  ) gt
• lt rb.getString("Welcome") gt
• WITH
• Localizer.getMessage ("Welcome") gt

17
Globalization compatibility between Java Oracle

• No Globalization Standard
• Lengthy lead time for Java to add new locale
  support
• The GDK extends Oracle Globalization Support
  features to the application server
• Handles the compatibility between the Java and
  the Oracle database server seamlessly

18
Not available in Java 1.4.2

• Character sets

• Languages

• Territories

• Linguistic Sorts
