Rapid development of Rich JSF Web applications on top of EJB/JPA persistence (JSF on Rails – Demo 1)
Here you will find the first demo from my Devoxx 2008 presentation. It shows how you can rapidly create a rich web application based on Java Server Faces and EJB/JPA persistency using JDeveloper 11g and the ADF 11g framework. The presentation included below shows the steps one by one to create a rich web application. The JDeveloper 11g application can be downloaded as well. The end result looks something like:
it includes such features as: master detail tables with synchronization; column sort; run time column manipulation: resize, reposition and hide/show; popup with detailed context data; data driven, synchronized chart; accordion for better page real estate usage.
EJB Dependency Injection of Session Bean Facade in JSF 1.2 on WebLogic 10.3 (JSF with JPA)
As I was preparing for my Devoxx presentation next Monday, I decided to look at the somewhat harder way of integrating a JPA based business tier into a JavaServer Faces web tier. The easy way – when using the ADF 11g framework in JDeveloper 11g is creating a Data Control for the Session Facade Bean. The Web Application can create data bindings for entities, entity collections and operations exposed in the Session Facade Bean that completely hide the injection or lookup details from the web tier developer. It’s the ADF responsibility to find the session bean and manage references to it.
However, if you do not use ADF, you need to establish the link between the Web Application and the JPA Business Service yourself.
The JEE 5 way of achieving this consists of a few simple steps – on top of the JPA entity definitions: (more…)
