EasyBeans

EasyBeans main goal is to ease the development of Enterprise Java Beans. It uses some new architecture design like the bytecode injection (with ASM OW2 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, Apache OpenJPA, TopLink Essentials or EclipseLink but other JPA providers have been tested like for example Datanucleus.

Apache Portable Runtime

The mission of the Apache Portable Runtime (APR) project is to create and maintain software libraries that provide a predictable and consistent interface to underlying platform-specific implementations. The primary goal is to provide an API to which software developers may code and be assured of predictable if not identical behaviour regardless of the platform on which their software is built, relieving them of the need to code special-case conditions to work around or take advantage of platform-specific deficiencies or features.

Apache HTTP Server

The Apache HTTP Server Project is an effort to develop and maintain an open-source HTTP server for modern operating systems including UNIX and Windows NT. The goal of this project is to provide a secure, efficient and extensible server that provides HTTP services in sync with the current HTTP standards.
