  4. 4. Compatible Java EE 5 Implementations 4
  5. 5. Java EE 6 Platform Goals • Rightsizing > Flexible > Lighter weight • Extensible > Embrace Open Source Frameworks • Productive > Improve on Java EE 5 5
  6. 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. 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 7
  8. 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. 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. 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 10

  12. 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. 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) { ... } 13

  15. 15. Java Enterprise Edition 6 Status • Most public reviews complete • JSR 330 Recently added > Revised schedule > Final release in Q4 2009 • GlassFish v3 Preview > Reference Implementation 15
  16. 16. Java Enterprise Edition 6 Servlet 3.0 • Annotations for ease of development • Optional web.xml • Better defaults • Web Framework pluggability • Asynchronous Processing 16
  17. 17. Java Enterprise Edition 6 Servlet 3.0 Asynchronous API • Useful for Comet, long waits • Must declare @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. 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. 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> 19
  20. 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 > Bootstrapping API EJBContainer 20

Java Enterprise Edition 6 Enterprise Java Beans 3.1 Features EJB 3.1 Lite EJB 3.1 Local Session Beans P P Declarative Security P P Transactions (CMT/BMT) P P Interceptors P P Security P P Message Driven Beans P RMI/IIOP Interop. & Remote View P EJB 2.x Backwards Compatability P Timer Service P Asynchronous P 21
  22. 22. Java Enterprise Edition 6 Additional Features • Java Persistence Architecture 2.0 > Improve object/relational mapping • Java Contexts & Dependency Injection (AKA - “Web Beans”) • Java Server Faces 2.0 > AJAX > Simplified component creation • JAX-RS 1.1 – RESTful services 22
