Globalization acronyms
Globalization [G1 1 n]
“Globalization addresses the business issues associated with taking a
product global. In the globalization of high-tech products this involves
integrating localization throughout a company, after proper
internationalization and product design, as well as marketing, sales, and
support in the world market.”
Internationalization [i1 8n]
“Internationalization is the process of generalizing a product so that it can
handle multiple languages and cultural conventions without the need for
re-design. Internationalization takes place at the level of program design
and document development.”
Localization [L1 0n]
“Localization involves taking a product and making it linguistically and
culturally appropriate to the target locale (
country/
region and language)
where it will be used and sold.”
Translation ===> T9n
3

How do they differ and relate ?
• Globalization at the architecture level
• Internationalization ( 8n)enables Localization
i1
• An expert in i1 8n may not be an expert in l1 0n
• I18n (code) + l10n(linguistic) + T9n (translation)
= G11n (process)

Internationalization support in Java
Java Platform is Internationalized
➢
Extensive library of classes and functions
●
I18n support comes for free or at very little cost
●
Built-in I18n support for over 70 languages
●
All text in a running Java program is Unicode
➢
5

Concept of Resource Bundle
6

Example Code: Before Internationalization
System.out.println(“Hello”);
System.out.println(“Sun Tech Days”);
System.out.println(“Hyderabad”);
7

Example Code: After Internationalization
Locale myLocale = new Locale(myLanguage, myCountry);
ResourceBundle messages =
ResourceBundle.getBundle(“messageBundle, myLocale);
System.out.println(messages.getString(“greeting”));
System.out.println(messages.getString(“event”));
System.out.println(messages.getString(“place”));
Your Resource Bundle property catalog file will have,
greeting=Hello
event=Sun Tech Days
place=Hyderabad

Introduction to AJAX
> AJAX = acronym for
Asynchronous JavaScript and XML
– Browser client uses JavaScript to Asynchronously
– get XML data from a server and update page
– dynamically without refreshing the whole page
> Why is AJAX so popular ?
– Increase Usability of Web Application
– Save Bandwidth
– Download only data you need
– End user Sequence and Faster interfaces
> Side effects of AJAX ?
– Breaks back button support
– URL's don't change as state changes
– Cross Browser Issues can be a pain
9

User Interface: Traditional Web Vs AJAX
10

Traditional Web AJAX
within a browser,
there is AJAX engine
11

AJAX Internationalization
• Server Side: By setting the appropriate Request
and Response Object to a right encoding in
Servlet controller
> In doGet method
– request.setCharacterEncoding(“UTF-8”);
> In sendResonse method
– response.setContentType(“text/xml;
charset=utf-8”);
> Using Resource Bundle for externalizing messages to
property files and naming them to appropriate locale
variant.
• Client Side: By setting your browser to UTF-8
encoding.
12

Introducing Portlet Application
> Specialized Web application that
provides value-added services like,
– Personalization, Single Sign-On,
Content Aggregation, Dynamic
Drag and Drop, Work From
Desktop, Search& Tagging.
> Portlet is a piece of markup called
as 'Fragment'
> A Portal Application can have
multiple portlets.
– Window functionalities like,
minimize, maximize, configure,
close..etc
> Portal Administration for Role, Look
& Feel, Permissions, SOA, JAI
> Includes Wikis, Message Boards,
Blogs, Email, IM, Activity Tracking,
Calendar, etc.. 13

Hindi Portal Application
14

Internationalizing your Portlet
> Server Side: By setting the appropriate Resquest and
Response Objects to right encoding in Servlet/JSP
controller.
– Adding locale support in your portlet.xml
<supported-locale>hi</supported-locale>
– JSP Page Directive
<%page contentType=”text/html; charset=UTF-8”%>
<%page pageEncoding=”UTF-8” %>
– Using JSTL FMT library
<% taglib uri=”http://java.sun.com/jsp/jstl/fmt”
prefix=”fmt” %>
– Setting Resource Bundle
<fmt.setBundle basename=”PackageName.BundleName” />
– Calling the tag lib in your JSP page
<fmt:message key=”name”/>
> Client Side: Set your browser encoding to UTF-8.
15

Let us start the LAB with Exercise 0
> Install Java SE 6 update 10 or above
> Install NetBeans 6.5 with GlassFish V2/V3
> Copy i18nHOL.zip and
unzip
– Will create i18nHOL
directory =
<lab_root>
– It contains the following:
– Start with index.html
– Exercises directory like

Lastly, let us take to JavaFX Lab Session

JavaFX Overview
JavaFX platform FX
●
JavaFX Desktop
●
● JavaFX Mobile and JavaFX TV
● Other devices and screens to follow
Tools Suite
●
JavaFX Developer (Plug-ins for IDEs, Media
●
converters, RAD tools)
● JavaFX Designer (Authoring, Video
Encoding)
Suite of Applications build on JavaFX
●
● JavaFX Content, Applications & Services
21

Single Virtual Machine/ byte code
22

JavaFX Script Programming Language
Declarative, statically-typed scripting language
>
Facilitates rapid GUI development
>
Many cool, interesting language features
>
Runs on Virtual Machine for the Java™ platform
>
Deployment options same as Java programs
>
Fully utilizes Java class libraries behind the scenes
>
For content designers and Media engineers
>
Supports primitive types like, String, Boolean, Number,
>
Integer, Duration.
> Supports Objects, Multiple Inheritance and any Java
Objects can be used in JavaFX.
23

Comparision of Java, Swing and JavaFX
24

Introducing Internationalization in JavaFX
> Creating a Locale Object
> Setting the default locale
> Create Resource Bundle property file as
“Main_hi_IN.fxproperties”
> Resource bundle messages are called just by
prefixing with '##'
> Reduces complexity! Compared to Java Resource
Bundle
25

Internationalizing Dates in JavaFX
> Supports Java printf-style formats
> Uses same Formatter as Java
> POSIX standard strftime spec.
26

Internationalizing of Dates in JavaFX
• Formats
– %tx – Locale's appropriate date representation
– %tX – Locale's appropriate time representation
– %tg – The last two digits of the week-based year (ISO 8601)
– %tG – Week-based year (ISO 8601)
– %tu – Day of week ( Monday is 1) [ 1,7 ]
– %tV – ISO 8601 Week number of the Year.
27

Looking at locale based sorting for JavaFX
> Create a List of words
> Create the Instance of Collator by specifying the
Locale.
> Define the function for Sorting and displaying the List
of words.
28

Locale based Sorting using Collator
> In sort function we will call Collections.sort, that sorts
the list of words in ascending order by giving the
words list and strength of the collator as arguments.
> Append the output to a variable.
> Display as,
29

Backup of JavaFX
37

JavaFX: Command Line Development
include <javafx-sdk>/bin in PATH
•
javafxc to compile
•
javafx to run
•
Relevant library files in <javafx-sdk>/lib are
•
automatically included in classpath as necessary.
Rest can be included with the -classpath option
> With packages
● javafxc -d . firstjavafxsphere/Main.fx
● javafx firstjavafxsphere.Main
> Without packages
● javafxc Main.fx
● javafx Main
