 ===== Gazing into my Crystal Ball =====
-A 4th edition of Eckel’s book covering the new language features in Java 1.5.
+Back in 2005 I made some predications:{{  :at-m42:crystal-ball.png|}}
-Consolidation and wide acceptance of MVC and ORM frameworks.
+  * A 4th edition of Eckel’s book covering the new language features in Java 1.5 came true.
-The rise of lightweight frameworks.
+  * Consolidation and wide acceptance of MVC and ORM frameworks came true.
-Penetration of AOP into mainstream OO development.
+  * The rise of lightweight frameworks largely happened and Ruby on Rails bought forth even more "lightweightness".
-EJB 3.0! (see next slide)
+  * Penetration of AOP into mainstream OO development hasn't quite happened yet.
-One of you will get rich marketing yourself as a Java EE architect!
+  * EJB 3.0 came out (see next slide)
+  * One of you will get rich marketing yourself as a Java EE architect -- may still come true!
+----
+When I have some time I may update this presentation to bring it up to the state-of-the-art in 2009.
 ===== EJB 3.0 =====
-Recognising that the interests of developers where poorly served by the last versions of the EJB specification, Sun has set up a working group to develop version 3.0 of the specifications.
+Recognising that the interests of developers where poorly served by the last versions of the EJB specification, Sun set up a working group to develop version 3.0 of the specifications.
-Early indications are:
-Inspired by XDoclet (itself inspired by .NET) EJB 3.0 will make extensive use of annotations (a new feature of Java 1.5) to reduce the need for so many interface files.
+The final spec is now in general release:
-Business components will be standard Java Objects.
+  * Inspired by XDoclet (itself inspired by .NET) EJB 3.0 makes extensive use of annotations (a new feature of Java 1.5) to reduce the need for so many interface files.
-It will be adopting some of the techniques developed for ORM for persistence support.
+  * Business components are standard Java Objects.
-More at http://www.theserverside.com/articles/article.tss?l=SimplifyingEJB3 and in the draft specification at http://java.sun.com/products/ejb/docs.html.
+  * It includes ORM for persistence support in the form of the Java Persistence API (JPA) which is similar to Hibernate in design.

+  * EJB version 3 was released in May 2006.
