 (OSS/J) initiative defines a technology specific set of API specifications. In addition to API specifi- cations, OSS/J also includes reference implementations, technology compatibility kits, and multitechnology profiles for OSS integration and deployment. The core business entities (CBE) model of shared information/data (SID) model that helps to provide a technology neutral implementations view of the NGOSS architecture is used by the OSS/J API specifications. The Java 2 Platform Enterprise Edition and EJB-based Application Architecture are the enabling technologies in OSS/J, used as tools for developers to easily develop applications. The J2EE plat- form offers faster solution delivery with a reduced cost of ownership. The Enterprise JavaBean (EJB) component architecture is designed to hide complexity and enhance portability by separating complexities inherent in OSS applications. Rapid integration and deployment of a new OSS application can be done by OSS through Java initiative's framework due to standard EJB components that are already equipped with connectors. Application integration capabilities are provided for server-side applications by APIs that are defined within the initiative using J2EE platform and EJB architecture. A standard set of APIs using Java technology for OSS and BSS can be defined and implemented by using OSS through Java initiative. Members of OSS/J are leveraging standards from 3rd Generation Partnership Project (3GPP), Mobile Wireless Internet Forum (MWIF), and the TeleManagement Forum (TMF) to Standard Interfaces implement common Java APIs and provide a source code that can be made freely available to the industry. OSS/J implementation groups include telecom equip- ment manufacturers, software vendors, and systems vendors that are formed to develop and implement interoperable and interchangeable components to build OSS applications. Addressing the lack of interoperable and interchangeable OSS applications for the OSS industry is the goal of the initiative. Developing and implementing
