Converting an EJB 2.0 Entity Bean to EJB 3.0: The Enterprise JavaBeans EJB 3.0 specification has facilitated the development of EJBs, by providing an annotations-based API in which the remote/local and home/local home interfaces are not required. The deployment descriptors that form the basis of an EJB 2.0 entity bean are also not required for deploying an EJB 3...; Tags: EJB 2.0, EJB, J2Ee, Application Servers, Middleware, Enterprise Software, Software Development, Software/Web Development, Software; White papers 2006-01-01
Component Inheritance in EJB 2.0: Component-based architectures eliminate a number of the limitations of object-oriented development. Enterprise JavaBeans EJB components offer a greater base for reuse and integration for Java developers than POJOs. However, to make the most of what they offer requires a shift in focus from development-oriented programming to the more flexible realm...; Tags: EJB 2.0, EJB, J2Ee, Application Servers, Middleware, Enterprise Software, Software Development, Software/Web Development, Software; White papers 2005-10-25

Migrating From EJB 2.x to EJB 3.0: The EJB 3.0 specification makes programming much simpler. It makes the container do more work and the developers do less work. It decreases the number of programming artifacts for developers to provide, eliminates the requirement to implement ejb callback methods, and reduces the complexity of the entity bean programming model....; Tags: Programming, EJB, J2Ee, Application Servers, Middleware, Enterprise Software, Software Development, Software/Web Development, Software; White papers 2007-01-23
What's New in EJB 3.0: This paper looks at the various new features introduced in the Enterprise JavaBean EJB 3.0 specification and how they'll make developing EJBs easier.

Taking JPA for a Test Drive: The Summer 2006 release of the EJB 3.0 specification delivers a much simplified but more powerful EJB framework that demonstrates a marked preference for annotations over traditional EJB 2.x deployment descriptors. Annotations, introduced in J2SE 5.0, are modifiers that can be used in classes, fields, methods, parameters, local variables, constructors,...; Tags: Annotation, EJB, J2Ee, Application Servers, Middleware, Enterprise Software, Software Development, Software/Web Development, Software; White papers 2006-11-01
Simplifying Development: The goal of Enterprise JavaBeans EJB 3.0 is to simplify the development of Java applications and standardize the persistence application-programming interface for the Java platform. EJB 3.0 directly addresses the primary drawback developers have identified in EJB 2.x: complexity. Enterprise JavaBeans makes developers' lives easier, by providing a clear, standard...; Tags: EJB, J2Ee, Application Servers, Middleware, Enterprise Software, Software Development, Software/Web Development, Software; White papers 2005-07-01
Reengineering of Database Applications to EJB Based Architecture: The advent and widespread use of Enterprise JavaBean EJB technology not only demands more reengineering support for legacy database applications, but also changes the reengineering practice.
