EasyBeans is an open-source Enterprise Java Beans (EJB) container hosted by the OW2 consortium. The License used by EasyBeans is the LGPL.
EasyBeans main goal is to ease the development of Enterprise Java Beans. It uses some new architecture design like the bytecode injection (with ASM ObjectWeb tool), IoC, POJO and can be embedded in OSGi bundles or other frameworks (Spring, Eclipse plugins, etc.).
It aims to provide an EJB3 container as specified in the Java Platform Enterprise Edition (Java EE) in its fifth version. It means that Session beans (Stateless or Stateful), Message Driven Beans (MDB) are available on EasyBeans.
The new persistence layer used by EJB 3.0 is now called Java Persistence API (or JPA). It replaces the CMP (Container Managed Persistence) model used by EJB 2.x. The default persistence provider used in EasyBeans is Hibernate Entity Manager or Apache OpenJPA but other JPA providers have been tested like for example Oracle TopLink Essentials.
- leave anything related to transport, communication to other layers- use this revised CEP to express and execute event-relevant logic, the purpose of which is to translate the ambient events into relevant business events- have these business events trigger business processes (however lightweight you want to make them)- have these business processes invoke decision services implemented through decision management to decide what they should be doing at every step- have the business processes invoke action services to execute the actions decided by the decision services- all the while generating business events or ambient events- etc.
The ActiveBPEL™ engine is a robust runtime environment that is capable of executing process definitions created for the Business Process Execution Language (BPEL) standard.
Consider an [arbitrary] piece of code. It's indoors, it's well behaved, and you can be proud of it. What is it about that code that you like? Is it elegant? Is it clever? Does it enable something? How would you measure the value of code?
Agile Modeling (AM) is a practice-based methodology for effective modeling and documentation of software-based systems. Simply put, Agile Modeling (AM) is a collection of values, principles, and practices for modeling software that can be applied on a software development project in an effective and light-weight manner. As you see in Figure 1 AM is meant to be tailored into other, full-fledged development methodologies such as XP or RUP, enabling you to develop a software process which truly meets your needs. The techniques of AM, in particular Agile Model Driven Development (AMDD), the lifecycle for which is depicted in Figure 2, enable you to scale agile software development to very complex situations.
