This is an overview how to build an OSGI EJB3 Server I gave at OSGIExpertsDay at JAX09.
The Server is build using:
Eclipse Equinox as OSGI Framework
Eclipse Riena for Remote OSGI Services
EasyBeans as OSGI EJB3 Container
Hibernate as JPA Provider
Clients are Rich Clients (Eclipse RCP)
The project is model-driven using UML (MagicDraw), EMF (Eclipse Modeling) and oAW (openArchitectureWare).
redView provides a Visibility Processor, Visibility Descriptors and Conflict Resolvers.
You can easy define the rules when to display a Composite or to insert a nested View.
This Screencast uses as Example an Association to a Superclass (Vehicle), where you have a Driver View displaying the Vehicle this Driver drives: a Car or a Truck. Don't write boilerplate of SWT Code - use redView's WYSIWYG Editor.
redview - Dynamic Views (not only) for Business Applications:
redView (Riena EMF Dynamic Views) - declarative UI Design combined with dynamic Rendering at Runtime.
redView can be used for RCP (Desktop) Enterprise Business Applications, as UI for Webservices or simply as Prototyping Tool.
redView can be integrated into MDSD using openArchitectureWare (Eclipse Modeling Projects: MWE, Xpand/Xtend, Xtext) to generate SWT Views from a Model (UML, Xtext, XSD, WSDL)
Class loading is widely viewed as one of the darkest arts in Java development. In this session, Jason Greene will provide insight into the how and why of Java SE, Java EE, JBoss Application Server, JBoss Microcontainer, and OSGi class loading. He will offer historical perspective by beginning with JDK internals and progress to the modern, modular class loader models in use today. In addition, Jason will cover common pitfalls and methodologies to avoid them.
Presenter: Jason currently leads the JBoss Application Server project, which is a popular open source application development platform. He is a member of the Java Community Process (JCP), and most recently the expert group of the Java EE and Contexts & DI specifications. During his tenure at Red Hat, he has worked in many JBoss Enterprise Middleware areas, including the application server, clustering, Web services, AOP, and security. His interests include concurrency, distributed computing, hardware, and programming language design.
