Networks change. Existing functionality is parsed in new ways to support new features. New nodes with new or modified abilities are added. Because of Service Gatekeeper’s highly modular design, exposing these new features to partners is straightforward. There are several ways to extend Oracle Communications Services Gatekeeper:
Entirely new communication services
New network plug-ins that can work with existing application facing interfaces
New application-facing-interface types (facades) for existing network plug-ins
New or reordered interceptors or policy rules
Integration with the existing network mechanisms with EDR listeners and SMNP MIBs.
The Platform Development Studio
To help operators and systems integrators, Oracle Communications Services Gatekeeper ships with the Oracle Communications Services Gatekeeper Platform Development Studio (PDS). The PDS comprises the following features:
In console mode, particularly for use with the Unit Test Framework
Run the Application Service Clients
Use the Network Simulators
Utilize the utilities such as the MBean browser and the JMS-based EDR listeners
Understand the example module and extend the PTE
Example Communication Service, including:
Source code
WSDLs
Build files
Example unit test
Example Subscriber SLA/Profile Provider
The Eclipse wizard
The developer supplies information to an Eclipse plug-in wizard, which automatically sets up an Extension Project. Included within this project can be a substantial amount of generated code, including:
The entire Access Tier, with the Web Service implementation and any callback modules (EJBs) that are necessary
Note:
The Eclipse wizard supports building communication services based only on Web Services application-facing interfaces. Both SOAP and RESTful facade types are supported.
Most of the code for the common services code in the Network Tier
A skeleton of the code required for the network plug-in layer of the Network Tier
A complete Javadoc reference
Specialized templates and Ant tasks
The Unit Test Framework, providing:
A base test class, derived from JUnit
Simple-to-use mechanisms for connecting to the Platform Test Environment
An example unit test bundled with the Communication Service Example
The Profile Provider SPI, which allows operators and integrators to create subscriber-centric policy, associating subscribers with service provider and application groups based on individualized subscriber preferences and permissions.
