Java EE 5.0 = (J2EE 1.4).next • Java EE 5 Theme: Ease of Development • POJO-based programming > More freedom, fewer requirements

• Extensive use of annotations > Reduced need for deployment descriptors > Annotations are the default

• Configure by exception > Reasonable defaults wherever possible

• Resource Injection • New APIs and frameworks > EJB3, JAXB 2, JAX-WS, JSF, ...

Specification Changes in Java EE 5 JAX-WS 2.0 & JSR 181 ● Java Persistence ● EJB 3.0 ● JAXB 2.0 ● JavaSever Faces 1.2 – new to Platform ● JSP 2.1 – Unification w/ JSF 1.2 ● StAX – Pull Parser – new to Platform, JSR 173 ●

“Various Interface21ers, including Costin and Juergen, have taken a look at GlassFish and given it the thumbs up.” Rod Johnson, Spring Framework Creator, Feb. 2007 [1]

[1]: blog.interface21.com, Feb. 2007

“... we were seriously stressed when IBM declared war with Geronimo and then HP got in the game against us too. Red Hat and JOnAS didn't scare us at all (really – not at all), nor did we worry about Sun's foray into the market. Oddly enough, of that group only Sun has managed to mount serious competition to JBoss.” Marc Fleury, JBoss founder, August 2007 [2]

[2]: news.com, August 2007

“Among major vendors, Sun Microsystems Inc., has dramatically improved its standing in this year's evaluation of applications servers for service-oriented architecture (SOA) and business process management (BPM)” Forrester Research, August 2007 [3] Sun and the GlassFish open-source community have delivered the first production-scale open-source Java EE 5 application server. This challenges the dominance of market leaders like Red Hat and IBM. Gartner, September 2007 [4] [3]: http://www.forrester.com/Research/Document/0,,37138,00.html, August 2007 [4]: http://www.gartner.com/DisplayDocument?doc_cd=152044&ref=g_rss, September 2007

What Is GlassFish? • A Java EE 5 compliant Application Server > GlassFish v1 is Sun AS 9.0 PE > GlassFish v2 is Sun AS 9.1

• Enterprise Quality > Sun Java System Application Server 9.x > Use it in production!

• Open Source > CDDL (like OpenSolaris, NetBeans) > GPLv2 (like Java and NetBeans)

• Community at http://glassfish.java.net > Sources, bug DBs, discussions at Java.Net > Roadmaps, Architecture Documents

GlassFish Adoption Stories http://blogs.sun.com/stories

• iTAC Software Manufacturing Execution Systems (MES) > using GlassFish to provide direct connection

between shop floor devices in manufacturing plants > 3 million calls a day: uses EJBs, rich IIOP clients, and the Java Connector Architecture

• Wotif.com

> Large # hits, 10,000 concurrent sessions, 1

million users/110,000 bookings monthly > Hibernate, Struts, Spring, and ehCache / Horizontal Scaling

• Harvard University

> On-line archive for sharing data within and

across universities > NetBeans, the Lucene search engine, PostgreSQL database, Shale standalone tiles

Some Adoption Indicators • +2.5M hits in 13 mo • +310K different IPs

• 88K Registrations in 4.5 months • +4.5 M downloads in last 12 months

JAX-WS, WSIT, and JAXB implementations

• Dynamic JAX-WS Runtimes • JAXB 2.0 fully support XML Schema > A lot of reuse of GlassFish's JAXB implementation

• GlassFish JAX-WS 2.x > Simple annotated POJO model > WS Separation of Transport and Encoding > HTTP, JMS, SMTP, TCP/IP > MTOM, Fast Infoset (binary), Textual, Others

• WSIT (Project Tango) > Microsoft Interoperability and Quality of Service > Same (old) JAX-WS programing model See “Metro and REST” presentation today @ 3:10

Dynamic Clustering and In-Memory Replication • GMS with Project Shoal

> http://shoal.dev.java.net > Dynamic clusters implemented with JXTA by default > Extreme ease of use in cluster setup

• Replication

> What? > HTTP session state > Stateful EJB session state > Single Sign-On state > Container state (timers, ...) > How? > Default is In-Memory replication with JXTA > Can still use HADB for 99.999% uptime (higher perf degradation)

jMaki • 'j' stands for JavaScript. Maki means to wrap in Japanese • Framework for encapsulating AJAX libraries and widgets from Dojo, Yahoo!, scriptaculous, Google, and more • Usable with JSP, JSF, PHP and Ruby on Rails • Easy to build your own widget • Common event model and proxy architecture • Automatic handling of JavaScript resource files • V 1.0 released • http://ajax.dev.java.net and http://widget.dev.java.net

Web Tier • JSP Container > 10x perf. improvement in JSP compilation (JSR-199)

• Grizzly > > > > >

Improved over GlassFish v1 Very Flexible and Customizable Non-blocking SSL, Quality of Service constraints Scalable Async Req Processing (ARP) Supports Comet (long-term HTTP connections)

• Hosting features > Alternate docroots > Webcontainer dynamically reconfigurable

Introduction to Grizzly What Is the Grizzly HTTP Framework?

• Grizzly is a HTTP framework > Uses lower level Java NIO primitives > Easy-to-use, high-performance APIs for socket

communications

• Grizzly brings non-blocking sockets to the HTTP processing layer • Grizzly integrates with the current Apache Tomcat HTTP Connector architecture (Coyote) > Coyote is currently used in Tomcat 3.x/4.x/5.x

• Grizzly replaces Apache Tomcat Coyote HTTP front-end and thread pool > Utilizes its high performant buffers and

parsing classes

Demo • Grizzly Comet and jMaki: interactive Flickr based Chat • Comet (request polling): > Builds on top of Grizzly ARP (Asynchronous Request Process) > Enables web servers to send data to client without client

request > Allows creation of event-driven web application which are hosted in browser

Java EE 6 – JSR 316 • Extensibility > Embrace and support popular frameworks and technologies

developed in external communities > Layer these technologies cleanly on top of Java EE platform

• Profiles > Rules for referencing Java EE platform technologies in Java EE

Profiles > A profile may include a subset of Java EE platform technologies, additional JCP technologies, or both

• Pruning > Define process of removing technologies from platform

• Goal is to deliver a final version by the end of 2008

Java EE 6 – Proposed New JSRs* • JSF 2.0 (JSR 314) • JAX-RS (JSR 311) > RESTful web services

• WebBeans 1.0 (JSR 299) – led by JBoss • Servlets 3.0 (JSR 315) • Enterprise Java Beans 3.1 > Singletons, Asynchrony, Concurrency options, ... > JavaBeans Validation framework (JSR 303)?

• Java Persistence API 2.0 > Criteria API, hierarchies in embeddables

• Java EE Connector 1.6 *The exact set of technologies to be included will be determined by the expert group

GlassFish v3 • Small, Fast, Modular > Less than 1.0 sec startup

• Totally Modular, kernel is <100K > Based on a module sub-system: HK2 (Hundred K Kernel) > Can run in a phone, in a desktop application or in-process

• An ideal Container for Web 2.0 > Java and Scripting applications > Support for upcoming Java EE 6 profiles

• A container that can do Java EE and more > Don't think of it as a Java EE 5 container > A good fit for SOA/ESB solutions

• Decomposition of the Java Platform, Enterprise Edition (Java EE platform) application server implementation

GlassFish v3 – Work in Progress • Sample Containers > > > > >

Java Web Container JRuby (no GoldSpike required) PHP (via Quercus) JavaScript (via Phobos) Whatever you decide!

• Code and documentation available today • Plans & Roadmap > Java Web profile likely in 1H2008

New Areas - GlassFish v3 • • • •

Modular, OSGi-based Lightweight, Fast StartUp, Scalable Embeddable and Extensible JavaEE 6 and Frameworks

• • • •

All JVM-Scripting Languages For Developers and Deployers, Education and Research New Partnering Opportunities From Very small to HA to Communication to Grid

GlassFish v3 • GlassFish, an Open Source application server built on and with Open Source components : > Maven 2 > build system > module description > Felix > OSGi module management > Eclipse Link > Java Persistence Architecture implementation

• V3 is the third open source release of GlassFish

GlassFish V3 modularity • Based on a module management runtime > last year : HK2 homegrown module management > today we add : OSGi Felix as the underlying module

management runtime.

• Modules are great but let's face it, they do nothing just being modules ! • V3 innovation : > allow any type of container to be plugged in. > start all containers and services on demand yielding an

unmatched startup time for a Java EE server. > focus on developer (keeping the already numerous deployer's features).

Services • GlassFish V3 use extensively Services to identify extension points like : > Application Containers (like Web-App, Phobos, Jruby...) > Administrative Commands

• Services are : > implementing an interface

> Java SE style with a META-INF/services file > OSGi style > HK2

• Can be stateless or statefull
