4. GlassFish around You

5. GlassFish around You (really)

6. GlassFish around You (really, really)

7. 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)

8. 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)
>

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

10. What is a
“lightweight”
Application Server ?
10

11. Tomcat ?
11

12. Fast startup ?
12

13. Load on-demand ?
13

14. Introducing
GlassFish v3 Prelude
14

15. Admin Console
15

16. 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

17. Demo
Startup
Compile on Save
Deploy on Change
Preserve Session
17

18. 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

19. 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

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

21. Update Center
21

22. 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

23. 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

24. 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

25. 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

26. Demo
simple ejb 3.1
war packaging
26

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

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

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