Learn to Internationalize your Applications - Sun Tech Days 2009 Learn to Internationalize your Applications - Sun Tech Days 2009 Presentation Transcript

  • Learn to Internationalize your Java, JavaFX, AJAX and Portlet Applications Shankar Gowda & Shrinath Hedge Globalization Engineering Sun Microsystems, Inc.
  • Agenda Globalization Overview > What's with acronyms and definitions ? > How do they differ and relate ? > Introducing Internationalization(i18n) in various technologies > Language Exercises (100 mins) > – Exercise 0: Setup Lab Environments – Exercise 1: Internationalize your Java application – Exercise 3: Internationalize AJAX Web application – Exercise 4: Internationalize Portlet application – Exercise 2: Internationalize JavaFX application > Tools, Summary and References 2
  • 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) 4
  • 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 8
  • 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 16
  • Excrcise 1: Learn to Internationalize your Java Application 17
  • Exercise 3: Learn to Internationalize your AJAX enabled Web Application 18
  • Exercise 4: Learn to Internationalize your Portlet Application 19
  • Lastly, let us take to JavaFX Lab Session 20
  • 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
  • Exercise 2: Learn to i18n JavaFXSphere • Install, Configure Lab environment • Creating a FirstJavaFXSphere Application • Internationalizing the code of FirstJavaFXSphere application • Externalizing the messages to Main_hi_IN.fxproperties • Localizing in Hindi 30
