Java EE 5 Overview

Java EE 5.0 Summary How is it easier? J2EE 1.4 Java EE Deployment Java language descriptors annotations @ Required container Plain Old Java interfaces Objects (POJOs) JNDI Lookups Dependency Injection Deployment descriptor, interfaces More and better defaults No Supported UI Framework Java Server Faces (JSF)

Catalog Sample Java EE Application Registration Application Managed Bean Entity Class Item DB ManagedBean Catalog Session Bean JSF Components

Entity Classes Use JPA to map/retrieve data from the database as Java Object Item ID NAME DESC URL @Entity public class Item { @Id int id; String name; String descr; String url; }

Catalog Statelesst eSession EJB, JPA Query e p e n d e n c y S t a l e s s S e s s io n D In j e c t io n B e a n A n n o t a t io n @Stateless public class Catalog implements CatalogService { @PersistenceContext(unitName=”PetCatalogPu”) EntityManager em; @TransactionAttribute(NOT_SUPPORTED) public List<Item> getItems(int firstItem, int batchSize) { Query q = em.createQuery ("select i from Item as i"); q.setMaxResults(batchSize); q.setFirstResult(firstItem); List<Item> items= q.getResultList(); return items; } }

Demo Netbeans 6.5 Glassfish v2 JAX-WS

RESTful Web Services with JAX-RS (JavaEE 6 but in Glassfish v2)

RESTful Catalog RIA App REST DataBase Registration Application Persistence-tier Web Services JAX-RS class Entity Class Item DB HTTP ItemsConverter ItemsResource JAXB class JavaFX

RESTful Catalog Web Service HTTP GET http://petstore/catalog/resources/items/ Ad d re s s a b l e Client Re s o u rc e s Response XML items Server We b <item> C o n t a in e r <imageurl>http://host/catalog/images/anthony.jpg</imageurl> <name>Friendly Cat</name> <price>307.10</price> <productid>feline01</productid> </item>

JAX-RS: Clear mapping to REST concepts High level, Declarative Uses @ annotation in POJOs Resources: what are the URIs? @Path("/items/{id}") Methods: what are the HTTP methods? @GET public XXX find() Representations: what are the formats? @Consumes("application/xml") @Produces("application/json")

RESTful Catalog Items Resource retrieves updates a collection of Item entities /items – URI for a list of Items Registration Application Item resource retrieves or updates one Item entity /item/1 – URI for item 1 JAX-RS class Entity Class Item DB HTTP ItemsConverter ItemsResource JAXB class JavaFX

Get Items resource responds to the URI http://host/catalog/items/ @Path("/items/") method public class ItemsResource { responds to HTTP GET Representation @GET @Produces("application/json") responds with JSON public ItemsConverter get(){ return new ItemsConverter( getEntities()); } Performs JPA Query, returns list of entities

Clustering And Load Balancing HTTP(S) JMS RMI/IIOP Runtime Cluster Message Routing / Failover / Load Balancing member discovery & health Management monitoring AS AS AS AS AS AS Instances Clustered through . . . AS Shoal Node A Node B Node C HA Application State Repository

Memory Replication for High Availability Example: Maximize Availability on 4 instance Typical cluster topology cluster on 2 nodes(machines) Instance 1 Instance 2 Instance 3 Instance 4 Machine 1 Machine 2

Comet: the server pushes data to the client over a long-lived HTTP connection GlassFish supports Comet Serve r Client Client 1 2

Ajax Push and HTTP keep-alive Comet: server pushes data to the client over a previously opened connection HTTP/1.1 Keep-Alive or Persistent Connection: keeps connection open until message or timeout Long Poll: Send a request to the server, request waits for an event, then response sent

GlassFish Grizzly Comet NIO: non-blocking sockets ARP Asynchronous Request Processing: Doesn't block a thread per http request availability of threads gives scalability

Java EE 6 and Future

Java EE Timeline Profiles Java EE 6 EJB Lite Ease of Restful WS Development Web Beans Java EE 5 Extensibility Web Ease of Services Development J2EE 1.4 Annotations ` Web Services, Robustness EJB 3.0 Management, Persistence API Enterprise Java J2EE 1.3 Deployment, New and Platform CMP, Async. Updated Connector J2EE 1.2 Connector Web Services Java EE 6 Servlet, JSP, Architecture Web Profile JPE EJB, JMS Project RMI/IIOP

Major new Features in Java EE 6 Profiles targeted bundles of technologies 1st profile is the Web profile Pruning older technologies optional CMP, JAX-RPC... Extensibility Zero-configuration, drag-and-drop for web frameworks Ease of development

Full JSRs Java EE 6 EJB 3.1 JPA 2.0 New Features Servlet 3.0 Profiles JSF 2.0 Pruning JAX-RS 1.0 Extensibility Connector 1.6 More ease of development Bean Validation 1.0 Web Beans Maintenance JSRs JAXB 2.2 JAX-WS 2.2 JSR-109 1.3 EL 1.2 JSP 1.2 Authentication SPI 1.1 Common Annotations 1.1

Ease Of Development Ongoing concern focus is the web tier General principles: Annotation-based programming model web.xml not required Self-registration of third-party libraries Simplified packaging

Web Profile Servlet 3.0, JSP 2.1, JSR-45 (Debugging), EL 1.2, JSTL 1.2, JSF 2.0 EJB Lite 3.1, JTA 1.1, JPA 2.0, JSR-250 (Annotations)

EJB “Lite” Small subset of EJB 3.1 API for use in Web Profile Lite Local Session Beans Also requires JPA 2.0 / JTA 1.1 API

Simplified Packaging EJB components can be packaged directly inside a web application archive (war file)

Some Servlet 3.0 Highlights Annotation-based programming model @WebServlet @ServletFilter etc. Async APIs Useful for Comet, chat rooms, long waits

Some JavaServer Faces 2.0 Features custom components easier to develop Ajax support Html templates (Facelets) Reduce configuration Bookmarkable URLs

Some EJB 3.1 Highlights Singleton beans: @Singleton No interface view: one source file per bean Calendar timers: @Schedule(dayOfWeek=“Mon,Wed”) Async business methods: @Asynchronous Simplified testing (embeddable test outside container)

Session Bean with Local Business Interface...OLD... HelloBean Client <<interface> com.acme.Hello @EJB String sayHello() private Hello h; ... h.sayHello(); com.acme.HelloBean public String sayHello() { ... }

Session Bean with no Interface @Stateless public class HelloBean { public String sayHello(String msg) { return “Hello “ + msg; } }

no Interface client...NEW... @EJB HelloBean h; ... h.sayHello(“bob”);

Timeline June 2007 Expert group formed Q3 2008 Public draft Q4 2008 Proposed final draft Q2 2009 Final release

GlassFish V3 – The Future

GlassFish v3 Java EE 5 = GlassFish v2 GlassFish v2.1: better, faster, more scalable GlassFish v3 Prelude Web Tier Only, OSGi Based, some EE 6 previews EclipseLink (JPA) Bundled Multiple Containers (jRuby, Groovy, Phobos) GlassFish v3 = Java EE 6 Work in Progress OSGi Based All have Netbeans and Eclipse Integration

What's new in V3 Modularity OSGi runtime (Apache Felix) Lightweight, Fast StartUp, Scalable Service based architecture services are defined by contracts and can be easily substituted lazy loading based on usage patterns Extensible not limited to traditional Java EE containers Embeddable Runs in-VM

GlassFish v3 JavaEE 6 and Frameworks All JVM-Scripting Languages small to HA to Communication to Grid Preview available today

GlassFish v3 Architecture Portlet Groovy JRuby OpenMQ OpenESB OpenSSO Container JMS Web Connection Java Container JSF Pooling (JCA) Metro EJB Container Persistence Management Console Update Center Management CLI Naming Grizzly Framework Monitoring/ Injection Configuration Serviceability/ Service Manager Logging GlassFish V3 Core Security (Module Subsystem) Transaction Deployment Clustering Management Service OSGi NetBeans Java SE JavaWebStart

GlassFish v3 Runtime GlassFish v3 is an OSGi application GFv3 is de-composed into a set of modules Modules are run inside OSGi container (Apache Felix) user-defined Webtier EJB Scripting JCAPS … modules user-defined … modules GlassFish Kernel (HK2, API, etc.) Felix runtime

Compile/Deploy on Change Java EE development doesn't have to be painful Incremental compile of all Java EE artifacts Auto-deploy of all Java EE and static artifacts Session retention: maintain stateful sessions across re- deployments

v3 Prelude Usage xWiki GlassFishV3 Project Fuji JavaDB SailFin (OpenESB.next) (Telco AppServer) WebSynergy (Portal, Liferay) EHCache Server WebEngine GlassFish v3 Embedded GlassFish v3 Embedded Jersey Jersey

Yes, Eclipse too ! GlassFish (v2/v3) + Eclipse 3.4 Tools Bundle: http://download.java.net/glassfish/eclipse/

GlassFish v3 Roadmap V3 Prelude Today! V3 Final aligned with Java EE 6 Starting a series of Milestone releases Targeted for Fall 2009 Clustering, central admin likely on the update center V3.1 full clustering Likely 6 to 9 months after V3
