This version contains the Open-Source Reference Implementation and Technology Compatibility Kit code that reflects final changes to the JSR 086 specification.
What is Enterprise Media Beans?
Enterprise Media Beans (EMB) is a rich media framework based on the JSR086 standard proposal for J2EETM-compliant applications; media is treated as just another data type. EMB enables applications to integrate rich media data, such as audio, video, or image, into applications based on Enterprise Java Beans (EJB) Entity BeansTM within the J2EE application development model. It allows the embedding of rich media assets into business logic without the worry about client type, server media protocols, media format, or streaming technology. It is a standardized, component-based application model for rich media integration throughout the enterprise -- back-end and infrastructure.
Today, rich media applications are developed using a collection of proprietary, non-standard APIs that are closely tied to specific implementations. An application programmer must choose an application platform, a content management system, and a rich media delivery system. Then, an application can be written to the APIs used by those solution components, but it cannot be easily ported or reused in a different environment. For example, if the application is written to use RealNetworks streaming servers, it is very difficult to switch over to Windows® Media. Furthermore, the programmer must learn the specific systems.
How does it work? EMB enables applications that primarily target the management and seamless integration of rich media data into EJB-based business applications. The pure-Java framework uses currently available products and technologies for storing, modifying, and rendering (especially streaming) media, while abstracting from their implementation and the different ways to access them. Because of the framework nature of EMB, new and upcoming products from various vendors can be integrated in a standard way, without necessarily affecting the business applications.
EMB Reference Implementation
The EMB Reference Implementation is available for download. It includes
- a reference implementation of EMB, including all the changes made in the final stages of approval of JSR 086 through the Java Community Process.
- a Technology Compatibility Kit (TCK) that can be used to validate the reference implementation or other implementations of EMB.
- removal of the media distribution beans function available in a previous technology preview
- a new sample application.
