GlassFish Adoption 3

GlassFish around You 4

GlassFish around You (really) 5

GlassFish around You (really, really) 6

All this .... ... with a boring application server (albeit with built-in full Web-Services Stack, full clustering, great monitoring tools, record performance, complete documentation, and heavily deployed in production) 7

GlassFish http://glassfish.org Best of class App Server • GlassFish v2.1 released Jan. 2009 > 4 millions downloads > Up to x2 usage over 12 months • Out of the box : “Grizzly”: scalable and innovative Web Tier > “Metro”: Complete Web Services interop with Microsoft > “Shoal”: Complete Java EE Clustering > Administration and monitoring tools > Performance (SPECjAppServer record) > Tooling (Best with NetBeans, Eclipse also supported) > 8

GlassFish Enterprise Manager • SNMP Monitoring • Performance Advisor • Self management Rules • Performance Monitor 9

What is a “lightweight” Application Server ? 10

Tomcat ? 11

Fast startup ? 12

Load on-demand ? 13

Introducing GlassFish v3 Prelude 14

Admin Console 15

Modular and Dynamic • Modular : Apache Felix (OSGi) • Extensible : HK2 • Yet very Fast ! Security Config Grails JRuby/Rails Web Naming Injection dispatch GlassFish Kernel browser Grizzly requests HK2 Services OSGi Runtime Bundles repositories services 16

Demo Startup Compile on Save Deploy on Change Preserve Session 17

Painless Java EE development ! • 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 18

Session Retention Deployment option to maintain stateful sessions across re- deployments $ asadmin redeploy --properties keepSessions=true myapp.war Greatly simplifies the development paradigm. Integrated in NetBeans 6.5 : 19

Yes, Eclipse too ! GlassFish (v2/v3) + Eclipse 3.4 Tools Bundle: http://download.java.net/glassfish/eclipse/ 20

Update Center 21

Prelude to Java EE 6 (via GlassFish Update Center) • JSF 2.0 Preview • EJB 3.1 Preview > Integrated Facelets > WAR packaging > First-class Ajax > Singleton support > No Interface View > Pub/Sub Events > TimerService > Composite > Asynchronous components operations > Better resource > ... handling • Servlet 3.0 soon > Groovy integration 22

JAX-RS (JSR 311) with Jersey • Making it easy to build RESTful Web services • Production-quality Reference Implementation @javax.ws.rs.Path(quot;/users/{id}quot;) public class UserResource { @javax.ws.rs.GET @javax.ws.rs.Produces(quot;text/xmlquot;) public String getUser( @PathParam(quot;idquot;) String userName) { ... } } • Final and supported v1.0 • Fine client API too 23

Servlet 3.0 • POJO > @WebServlet > @ServletFilter > @WebServletContextListener • web.xml now optional and supports fragments • Support for asynchrony > @WebServlet(asyncSupported=true) > New APIs for Servlet request and response for suspend, resume 24

EJB 3.1 Sample import javax.ejb.Singleton; import javax.servlet.WebServlet; @WebServlet(urlMapping={quot;/Counterquot;}) @Singleton public class SimpleServlet { public class CounterBean { @EJB CounterBean counterBean; private int hitCount; void processRequest(...) { try { public synchronized int incrementAndGetHitCount() { ... return hitCount++; counterBean.incrementAndGetHitCount()); ... } } finally { out.close(); } } } } 25

Demo simple ejb 3.1 war packaging 26

GlassFish Embedded AppServer glassfish = new AppServer(8080); glassfish.deployWar(warFile); 27

GlassFish Embedded public class Main { public static void main (String[] args) { AppServer glassfish = new AppServer(8080); glassfish.deployWar(warFile); } } 28

GlassFish Embedded @BeforeClass public static void setUpClass () { AppServer glassfish = new AppServer(8080); glassfish.deployWar(warFile); } @Test public void pingApplication () { ... } 29

A lot more ... Langages dynamiques: Rails, Grails, Django, ... • Comet, Cometd/Bayeux • Support complet de mod_jk, WebDAV, CGI, SSI • Web Services Metro 1.4 (.Net 3.5) • console user IPS/pkg(5) • Central Config domain.xml Admin Console Admin RESTful • C Container Monitoring • o GUI Parts Runtime n f Extensibilité • Grizzly Adapter i Admin commands g > Moteur Kernel > Console admin > Fichier de config client/browser admin invocation 30

GlassFish v3 Prelude – Practical • Get it from http://glassfish.org • Download size: 26MB > Graphical Installer > Zip version > Community-contributed IzPack installer • Choice > Eclipse or NetBeans > Runs on Java 5 and Java 6 (Java EE 6 will mandate Java 6) > Felix or Equinox • Questions and feedback to : USERS@glassfish.dev.java.net or GlassFish forum. • Supported product, subscriptions available 31
