5. Java EE 6 Platform
Goals
• Rightsizing
> Flexible
> Lighter weight
• Extensible
> Embrace Open Source
Frameworks
• Productive
> Improve on Java EE 5

6. Rightsizing the Platform: Profiles
Platform Flexibility
• Decouple specifications to
allow more combinations
• Expand potential licensee
ecosystem
• Profiles
> Targeted technology bundles
> Web Profile
6

7. Rightsizing the Platform
Web Profile
• Fully functional mid-sized
profile
• Actively discussed
> Expert Group
> Industry
• Technologies
> Servlet 3.0, EJB Lite 3.1, JPA 2.0, JSP
2.2, EL 1.2, JSTL 1.2, JSF 2.0, JTA 1.1,
JSR 45, Common Annotations

8. Rightsizing the Platform
Pruning (Deprecation)
• Some technologies optional
> Optional in next release
> Deleted in subsequent release
> Marked in Javadocs
• Pruning list
> JAX-RPC
> EJB 2.x Entity Beans
> JAXR
> JSR-85 (Rules based Auth & Audit)
8

9. Rightsizing the Platform
Extensibility
• Embrace open source
libraries and frameworks
• Zero-configuration, drag-n-
drop web frameworks
> Servlets, servlet filters
> Framework context listeners
are discovered & registered
• Plugin library jars using Web
Fragments
9

10. Ease of Development
Extensibility
• Continue Java EE 5 advancements
• Primary focus: Web Tier
• Multiple areas easier to use: EJB 3.1
• General Principles
> Annotation-based programming model
> Reduce or eliminate need for
deployment descriptors
> Traditional API for advanced users

12. Ease of Development - Annotations
Servlet in Java EE 5: Create two source files
/* Code in Java Class */ <!--Deployment descriptor web.xml
-->
package com.foo; <web-app>
public class MyServlet extends
HttpServlet { <servlet>
public void <servlet-name>MyServlet
doGet(HttpServletRequest </servlet-name>
req,HttpServletResponse res) <servlet-class>
com.foo.MyServlet
{ </servlet-class>
</servlet>
... <servlet-mapping>
<servlet-name>MyServlet
} </servlet-name>
<url-pattern>/myApp/*
</url-pattern>
</servlet-mapping>
... ...
</web-app>
}
12

13. Ease of Development - Annotations
Java EE 6 Servlet: Single Source file (many cases)
package com.foo;
@WebServlet(name=”MyServlet”, urlPattern=”/myApp/*”)
public class MyServlet {
public void doGet(HttpServletRequest req,
HttpServletResponse res)
{
...
}

@WebServlet(asyncSupported=true)
• Then Call
AsyncContext ctx = ServletRequest.startAsync(req, res)
• AsyncContext can then either:
dispatch(String path)
start(Runnable action)
• Then paired with complete()
17

18. Java Enterprise Edition 6
EJB 3.1
• Ease-of-use improvements
• No-interface view
> Once source file per bean
• EJB inside web applications
> No ejb-jar
> Use WEB-INF/classes
> Shared component environment
• Portable JNDI
18

19. Java Enterprise Edition 6
EJB 3.1
• Singleton beans: @Singleton
> Shared state
> One instance per bean per JVM
> Container/Bean managed security
@ConcurrencyManagement
• Lightweight asynchronicity
> Async business methods
@Asynchronous
> Methods must return
void or Future <T>

20. Java Enterprise Edition 6
EJB 3.1
• Enhanced EJB Timer Service
> Cron-like scheduling
> Initialization-time timer creation
@Schedule(dayOfWeek=”Mon/Wed”)
• Embeddable EJB Container
> Use in JavaSE environments
