This document discusses JBoss Application Server 5. It provides a brief history of JBoss AS and describes some of the key features and innovations in JBoss AS 5.0.x and 5.1.x, including the JBoss Microcontainer, Web Beans, and Embedded Jopr. It also mentions some ongoing work and highlights other areas like JBoss Messaging, clustering, and security. The document distinguishes JBoss AS from JBoss EAP and discusses how EAP is forked from stable versions of JBoss AS. It provides some web resources for following JBoss developments.

7. JBoss Microcontainer
• Refactoring of JMX MicroKernel
– Service management
– POJO deployment
– Also standalone use
• A complete IoC framework
• Tight JBoss AOP integration
• Virtual deployment framework
– Deployment dependencies
– Structural deployers
Classloading
– Aspectized deployers Managed
– Deployment stages
• Fully extensible Deployers VFS

8. WebBeans – JSR299 RI (1)
Fill in a gap in JavaEE: shared component
among web tier and transactional tier.
JSR-299 defines a unifying dependency injection and
contextual lifecycle model for Java EE 6
• a completely new, richer dependency management model
• designed for use with stateful objects
• integrates the “web” and “transactional” tiers
• makes it much easier to build web applications using JSF and
EJB together
• includes a complete SPI allowing third-party frameworks to
integrate cleanly in the EE 6 environment
• provides a typesafe approach to dependency injection
JSR299 was heavily influenced by Seam and Google Guice.
The Expert Group is lead by Red Hat.

9. WebBeans – JSR299 RI (2)
What can be injected?
• Pre-defined by the specification:
– (Almost) any Java class
– EJB session beans
– Objects returned by producer methods
– Java EE resources (Datasources, JMS topics/queues,
etc)
– Persistence contexts (JPA EntityManager)
– Web service references
– Remote EJBs references
• Plus anything else you can think of!

10. WebBeans – Simple examples
@Current is the default
public class Printer { (built-in) binding type public class Hello {
public String hello(String name) {
@Current Hello hello;
return "hello" + name;
public void hello() { }
System.out.println( hello.hello("world") ); } Java Bean
}
} @Stateless
public class Hello {
public String hello(String name) {
public class Printer { return "hello" + name;
Mark the constructor to be
private Hello hello; called by the container }
} EJB 3
@Initializer
public Printer(Hello hello) { this.hello=hello; }
public void hello() {
System.out.println( hello.hello("world") );
}
}
Constructors are injected
by default; @Current is
the default binding type.

11. WebBeans – Names
@Named("hello") By default not available through EL.
public class Hello {
public String hello(String name) {
return "hello" + name;
}
} If no name is specified, then a
default name is used. Both these
beans have the same name
@Named
public class Hello {
public String hello(String name) {
return "hello" + name;
} <h:commandButton value=”Say Hello”
action=”#{hello.hello}”/>
}
JSF page
Calling an action on a bean through EL

12. WebBeans – Binding type
We specify the @Casual binding type,
otherwise @Current would be assumed
@Casual Creating a binding type is easy...
public class Hi extends Hello {
public String hello(String name) { public
@BindingType
return "hi" + name;
@Retention(RUNTIME)
} @Target({TYPE, METHOD, FIELD, PARAMETER})
} @interface Casual {}
public class Printer { Here we inject the Hello bean
@Casual Hello hello; and require an implementation
which is bound to @Casual
public void hello() {
System.out.println( hello.hello("JBoss") );
}
}

13. WebBeans – Deployment type
Same API, different implementation
@Italian
public class Buongiorno extends Hello {
Creating a deployment type is easy...
public String hello(String name) {
return "Buongiorno " + name; public
} @DeploymentType
} @Retention(RUNTIME)
@Target({TYPE, METHOD})
@interface Italian {}
<Beans>
<Deploy>
<Standard />
A strongly ordered list of enabled deployment types.
<Production>
Notice how everything is an annotation and so typesafe.
<i8ln:Italian>
</Deploy>
</Beans>
Only Web Bean implementations which have enabled
deployment types will be deployed to the container.

14. WebBeans – Much more...
• Scopes and contexts:
Loose coupling
– @SessionScoped
– @ConversationScoped
– @RequestScoped
Decouple technical concerns
– custom ... from business logic
• Interceptors: eg. @Transactional
• Events: Decouple event producers
from event consumers
– @Observes
– @Observable Allow business concerns
to be compartmentalized
• Decorators: @Decorator
• ...

15. Management console
Home page: http://jboss.org/embjopr
Demo: http://jboss.org/embjopr/demo

fun and spread the word :-)

21. JBoss AS vs. JBoss EAP
• A Fedora/RHEL type of split for JBoss
• Community Project (JBoss AS)
– JBoss As We Know It
– Sponsored by JBoss/Red Hat
– Allow innovation at a faster pace
• Enterprise Application Platform (EAP)
– Forks the community project at stable points
– Integrates with JBoss Developer Studio / JBoss Operations
Network
– Rigorously tested (performance, scalability, SpecJ, etc.)
– Certified on 17 OS and JVM combinations, 5 DBs
– 3 month Cumulative Patch cycles
– Supported for 5 years.
