Presenting the Adapters

Server/JavaTM data sources provide an adapter for each data source to be represented graphically, as show in this table:

Data Sources Adapters
Server/Java Data Source	Data Source	Adapter
Swing data sources
List data source	Java Swing JList/ JComboBox	IlsListDS2JListAdapter and IlsListDS2JComboBoxAdapter
Table data source	Java Swing JTable	IlsTableDS2JTableAdapter
Tree data source	Java Swing JTree	IlsTreeDS2JTreeAdapter
Rogue Wave JViews data sources
Graph Data Source	Rogue Wave JViews IlvGrapher	IlsGraphDS2IlvGrapherAdapter
Gantt data source	Rogue Wave JViews Gantt charts	IlsGanttDS2IlvHierarchyChartAdapter
SDM Data Source	Rogue Wave JViews SDM	IlsSDMDS2IlvSDMViewAdapter

To create a Server/Java data source, you must:

1. Write a specification file to define a dynamic view and load it in the server. This specification file must follow predefined naming conventions to enable the representation objects to be mapped to the data sources.

2. Create a Java GUI and connect the graphic objects to the appropriate data sources through the corresponding adapters. The connection can be made with Java IDE supporting JavaBeans.

3. Open the dynamic view on the server.

Connecting Java Data Sources to a Java GUI

Adapters connect Java data sources to a Java GUI. These adapters operate in two ways:

Data Sources (Server) to GUI: Server notification.

GUI to Data Sources (Server): User interface updates.

The adapters provided with the Rogue Wave Server libraries can be extended or reimplemented by the user. Adapters are connected to Java Swing gadgets or with Rogue Wave JViews gadgets. However, the architecture of the adapters is designed to be run in a multithread-safe Swing-based application. Practically, the adapters work by buffering the notification messages sent by the server. Those messages are processed later in the Swing thread dedicated to graphical updates. See Java Data Source Adapters for additional information.
