Detailed Description

Implementation of the server.

The implementation of the HSS server

The server implementation is based on open different open source projects

• Apache Struts for the web based administration gui.
• Hibernate for the persistence layer
• Apache Tomcat as container for the administration site.

Package and Layer overview

The implementation of the HSS is a multilayered implementation. This has been done to seperate the gui from the logic and to keep parts exchangable.

GUI Layer

The GUI Layer is realized using the Struts Web Framework. The classes for the GUI Layer are located in the web Package.

The form package contains the Struts form classes, which are holding the data page data during the session. The action package contains all the Struts actions which handle the Http requests.

Business Logic Layer

The classes from the op package implement the business logic for the model classes. These are used by the Server and the GUI layer to present data and to handle the user input.

Persistence Layer

The persistence layer was implemented using the Hibernate persistence framework. There are POJO's in the model package which were mapped to database tables. The use of Hibernate enables you to change the database for the HSS.

The data objects are referenced by the GUI Layer to present the data, and by the Business Logic Layer to perform the business logic.

HSS Layer

This layer provides the implementation of the HSS interfaces. It contains the implementation of the Cx, Sh and Zh interfaces. This implementation is directly referenced by the business logic to dispatch the user interactions to the diameter peer.
