Agenda

● JavaTM SE 6 - MustangSystemic properties

New features● JavaTM EE 5● Futures


Scripting

● JSR-223 defines framework for scripting engines● lets people plug-in new languages● and call into the JavaTM platform

● Sun is co-pckaging JavaScriptTM language support● using the Rhino engine from Mozilla

● Scripting project on java.net adds many others● currently has 12+ plug-ins

● for Groovy,Jelly, Python, Ruby, Scheme, Tcl, ...● plus links to BeanShell and PHP plug-ins

● all available for use with Mustang● see scripting.dev.java.net

TS-1382Fr. 10:45


Example: Application configuration

● import java.io.*;● import javax.script.*;●

● public class MyApp {●

● public static void main(String[] args) {● //...● ScriptEngineManager sem = new ScriptEngineManager();● ScriptEngine e = sem.getEngineByName("JavaScript");● FileReader fin = new FileReader("MyApp.config.js");● e.eval(fin);● // ...● } ● }


Scripting: JavaScript to JavaTM APIs

● // JavaScript configuration file for MyApp

● importPackage(java.lang)● importPackage(Packages.com.kgh.myapp);

● System.out.println("Running Graham's config script")● MyApp.setFavoriteMammal("lemur")


Desktop Foci● Look-and-Feels

● significant upgrades for Windows and Gnome● including support for Vista● antialiased LCD fronts, Grey Rect fix, ...

● Performance● boosts for Java2D pipelines (and Swing generally)

● Assorted API upgrades● SwingWorker, JTable sorting, GroupLayout

● Desktop Integration● icons in system tray, splash screen support● ability to launch native tools

2006 JavaOneSM Conference | Session 1076 | 19

DEMODesktop Integration


Windows Vista Status● Windows Vista is a key target platform

● We're tracking it closely● Mustang will include core Vista support

● Including IE7 plug-in, Vista look-and-feel, etc● All available when Vista ships in November● Key updates will go into Mustang Beta2 in June● Please help test your applets on Vista + Mustang β2!

● 1.4.2 and 5.0 will also support Vista in Nov.● But with older UI and more limited plug-in support● Extra support in updates (if needed)● Mustang will be primary focus for Vista integration


Web Services: JAX-WS● Goal: heterogeneous distributed programming

● successor to CORBA, RMI, DCOM, ...● easy-to-use, with rich types and flexible semantics● finally everyone is using the same core protocols

● including Microsoft!

● Mustang delivers full JAX-WS client ● and lightweight server (for callbacks)● JavaTM EE 5 adds richer server support

TS-1194We. 11:00


Web Services: Java and .NET


JAX-WS and Project Tango

● JAX-WS 2.0 delivers WS-I basic interop● adequate for basic scenarios● with simple security model

● Project Tango adds richer protocol support● With richer security models, better quality-of-service , etc.● WS-Security, WS-Trust, WS-ReliableMessaging, ...● Without changing the JAX-WS APIs.

● your existing apps will benefit without changes!● Sun JavaTM team is working closely with Microsoft

● Will be delivered on top of Mustang and Java EE 5 in 2007 TS-4661 Tu. 2:00

JavaTM EE 5 Overview


Java EE 5 is Done!


JavaTM EE 5 Platform Vendors


JavaTM EE 5 IDE Vendors


JavaTM EE 5 Goal

Make it easier to develop Java EE applications

Especially when first getting started with Java EE


How did we make it easier?● Declarative programming

● Originally - deployment descriptors● Now - Java language annotations

● Remove requirements● Plain Old Java Objects (POJOs)● More and better defaults

● More powerful frameworks● Less work for you to do

● Easier to learn and more productive!


Annotations in JavaTM EE 5● Made extensive use of annotations

● For defining and using web services● To map Java classes to XML● To greatly simplify EJB development● To map Java classes to databases● To specify external dependencies● To reduce need for deployment descriptors

● Just starting to scratch the surface of what's possible


JavaTM EE 5 Major Features● Simplified web services support● More web service standards support● Dependency injection● Greatly simplified EJBTM development● New JavaTM Persistence API● Easy web applications with JavaServerTM Faces

● And fully compatible with J2EE 1.4

JavaTM Persistence API● Single persistence API for Java EE and Java SE● Developed by EJB expert group

● Builds on years of experience with existing technologies and products

● Much simpler than EJB CMP● Feedback is overwhelmingly positive● At least three implementations (all open source):

● Oracle – GlassFish/TopLink Essentials● JBoss – Hibernate● BEA – Kodo/OpenJPA TS-3395

Dependency Injection● Example of Inversion of Control● Container “injects” resources...

● DataSource, EJB ref, web service ref, persistence units, UserTransaction, env entries,...

● ... into application ...● Fields, methods; public, private, or protected

● ... in container-managed classes● EJBs, servlets, JSF managed beans, web service

endpoints, handlers, interceptors, app clients● Avoids the need to use JNDI

TS-1969Wed. 4:00


J2EE 1.4 Resource Lookup● public class MyEJB implements SessionBean {

private DataSource myDS;public void ejbCreate() {

try {InitialContext ctx = new InitialContext();

myDS = (DataSource)ctx.lookup(

“employeeDatabase”);} catch (NamingException ex) {

// XXX – what to do?}

}...

● }

● Plus corresponding deployment descriptor entry


Dependency Injection● package com.example;● @Session● public class MyEJB {

@Resourceprivate DataSource myDS;...

● }

● Declares a resource named com.example.MyEJB/myDS● And injects it into the myDS field● No deployment descriptor entry needed!



@Resource(name = “employeeDatabase”)private DataSource myDS;...

● }

● Declares a resource named employeeDatabase● And injects it into the myDS field● Still no deployment descriptor entry needed!



@Resource(mappedName = “OracleDatabase”)private DataSource myDS;...

● }

● Declares a resource that's mapped to the app server's global resource named OracleDatabase

● And still no deployment descriptor entry needed!


JavaServerTM Faces 1.2● The Java EE Standard Web Application Framework

● Dependency injection in managed beans● Easy to use, powerful, extensible Expression Language,

shared with JSP● Large market of JSF components

● Over 200 components from over 20 vendors, such as...● Apache, BusinessObjects, ESRI, Oracle, Sun, etc.● Including AJAX support

● Java BluePrints AJAX Components● http://blueprints.dev.java.net

Application Packaging● Packaging is now much simpler● Many cases don't require deployment descriptors

● EJB jar file● Web application using only JSP, web services● Application client● Enterprise application (ear file)


Web Application Packaging Example● app.war

index.jspimages/logo.gifWEB-INF/classes/MyWebService.class

● That's it!● No META-INF/web.xml● No META-INF/webservices.xml● No JAX-RPC mapping file


Enterprise Application Packaging● Rules and conventions make for simpler packaging● .war files are web applications● .rar files are resource adapters● lib directory contains shared jar files● .jar with Main-Class is an app client● .jar file with @Stateless is an EJB


Enterprise Application Packaging Example● app.ear

lib/shared.jarui/web.warui/client.jarbiz/ejb.jar

● That's it!● No META-INF/application.xml

● J2EE 1.4 – 67 classes, 3284 lines of code● Java EE 5 – 43 classes, 2777 lines of code● 36% fewer classes to manage!

● RosterApp2

Java EE Futures● Still too early to say anything definitive● Everything is subject to approval by the JCP● We need feedback from you!

● What's most important to improve● What's most important to add● What is still not easy enough● What did we get right!


Java EE Futures● Grow upwards

● Composite applications● JBI, SCA

● Portlets● High availability, clustering, etc.

● Grow downwards● Scripting

● JavaScript in JSP pages, servlets● Web/application hosting, WebDAV

● Grow sideways● Improve existing APIs● AJAX● WS-*


JavaTM EE Summary● Java EE 5 is much easier● Download the SDK

● http://java.sun.com/javaee● Get involved in the GlassFish community

● http://glassfish.dev.java.net● Please give us feedback

● [email protected]● http://forum.java.sun.com


Agenda

FuturesJavaTM SE 7+ new language technologies


Dolphin: JavaTM Language Updates ● We're cautious in changing the JavaTM language

● the current language works really well!● but some thoughtful change seems good

● Direct support for XML● under active investigation● allows XML literals inline + simple queries

● “Super-Packages” (JSR-292)● formerly known as “friends”● complements runtime module work (JSR-277)

● Probably some others● a number of candidates being considered


XML in JavaTM, Candidate Syntax●

● String mark = "Mark Reinhold";● XML speaker = <who> { mark } </who>;

XML talk = <session> { speaker } <title> { "XML in Java" } </title> <when> { "Wednesday 1:30pm" } </when> </session>;

TS-3441 We. 1:30


JavaTM Modules Draft Syntax

● super package com.sun.myModule {●

// super-package exports:export com.sun.gilad.myapi.*;export com.sun.gilad.util.Helper;

// super-package members:com.sun.gilad.myapi;com.sun.gilad.util;com.sun.gilad.impl;

● }

TS-3885We. 12:15


Some Other Key Dolphin Candidates...● Desktop improvements:

● More Java2D graphics acceleration● Swing support for beans binding (JSR-295)● Swing application framework support (JSR-296)

● JavaTM Module System (JSR-277)● Better packaging● Including package repository

● BeanShell (JSR-274)● Yet more systemic enhancements● ... and we have many more candidates!

TS-3439 Tu. 2:00


Growing the Java platform● We want to grow the platform in several dimensions

● Ease-of-Development simplifies Java Platform APIs● but there are also a range of language styles

Different Places, Different Languages● JavaTM language is Gold Standard for enterprise coding

● Great for robust, long-lived, maintainable apps● But diversity is good!

● Lightweight apps may not need static checking● Fast-changing presentation tier can use different styles

● Advice:● Use Java language for long lived core business classes● Consider Scripting/Dynamic for fast-changing preso tier

● call into Java classes for business logic● Supports mixed mode development● Different styles for different needs, on shared Java Platform


Dynamic Languages● Dynamic languages run on the JVM today

● Ruby, Python, Groovy, many more● Happiness!

● New bytecode will accelerate dynamic languages● JSR-292 “Supporting Dynamically Typed Languages”● Supports more dynamic method dispatch● Make JVM support easier and faster

● The first JVM bytecode not used by JavaTM language!

TS-3886Th. 9:45


Visual Basic for JavaTM

● Goal: enable VB developers to use JavaTM platform● Semplice project will support VB language

● compile from VB source into Java classfiles● VB source code calls into Java platform APIs.

● A new language for the Java platform!● Will support standard VB.net concepts

● goal is to reuse basic VB skills● not to be an exact clone of all details of language

TS-3576 Th. 9:45


DEMOVB for Java


Web Tier Futures: Even More Ajax● We expect two long-term styles with Ajax● High-level JSF/Ajax components

● using JavaScript behind the scenes● for both whizzy effects and powerful server interaction

● Raw Ajax: hand written client JavaScript● increasingly using toolkits: Dojo,Kabuki,Prototype, ...

● JavaTM Web Tier will support both styles● tools support will be increasingly important● we'll try to work with others towards consensus styles● this area looks like seeing continuing change


JavaScriptTM in WebTier

● Project Phobos adds JavaScriptTM to JavaTM web-tier● complements client-side Ajax JavaScript

● JavaScript enabled pages● an extra language choice for JSP pages● lets you embed server-side JavaScript on pages● use JavaScript on both client and server!

● Lightweight servlets in JavaScript● Invoke JavaScript on incoming POST and GETs

BOF-9450Tu 9:30pm

Conclusion● JavaTM EE 5 is here now

● It is a no-brainer for new projects● Get it now!

● Mustang arrives in October● Many systemic upgrades and great new features

● Lots of work happening around new languages● Use scripting with Mustang

● Help get the word out!● Give this presentation to your colleagues!
