An application interacts with a connector through an instance of the
ConnectorFacade class. The following diagram shows the creation and configuration of the connector facade. The components shown here are described in more detail in the sections that follow.
The connector facade is instantiated and configured in the following steps:
The application creates a
LocalConnectorInfoManagerinstance (or instances) and adds the individual connector bundles (or assemblies).
LocalConnectorInfoManagerprocesses these bundles or assemblies to instantiate a
To be processed by the connector info manager, the connector bundle or assembly must have the following characteristics:
- Java Connector Bundle
META-INF/MANIFEST.MFfile must include the following entries:
ConnectorBundle-FrameworkVersion- Minimum required ICF Framework version (either 1.1, 1.4, or 1.5)
ConnectorBundle-Name- Unique name of the connector bundle
ConnectorBundle-Version- Version of the connector bundle
The combination of the
ConnectorBundle-Versionmust be unique.
The connector bundle JAR must contain at least one class, that has the
ConnectorClassannotation and implements the
- .NET Connector Assembly
AssemblyInfo.csis used to determine the bundle version, from the
The bundle name is derived from the
Nameproperty of the assembly. For more information, refer to the corresponding Microsoft documentation.
If you change the name of your assembly, you must adjust the
bundleNameproperty in your connector configuration file, accordingly.
The connector assembly DLL must contain at least one class, that has the
ConnectorClassAttributeattribute and implements the
For each connector, the
MessageCatalog, which contains the localized help and description messages for the configuration, and any log or error messages for the connector.
Your application can use this information to provide additional help during the connector configuration process.
For each connector, the
LocalConnectorInfoManagerthen processes the
ConfigurationClass, to build the configuration properties for the connector.
Your application finds the connector info by its connector key. When the application has the connector info, it creates an API Configuration object that customizes the following components:
Object pool configuration
Result handler configuration
The API Configuration object is described in more detail in The API Configuration Object.
ConnectorFacadetakes this customized API configuration object, determines which connector to use and how to configure it, and implements all of the ICF API operations.
Applications access the connector API through a
ConnectorFacade class, and interact with the connector through a
The following steps describe how to create a
ConnectorFacade in your application.
ConnectorInfoManagerand acquire the
ConnectorInfoobject for your connector, as described in the previous section.
ConnectorInfoobject, create the default
APIConfiguration apiConfig = info.createDefaultAPIConfiguration();
Use the default
APIConfigurationto set the
ConfigurationProperties properties = apiConfig.getConfigurationProperties();
Set all of the
ConfigurationPropertiesthat you need for the connector, using
properties.setPropertyValue("host", SAMPLE_HOST); properties.setPropertyValue("adminName", SAMPLE_ADMIN); properties.setPropertyValue("adminPassword", SAMPLE_PASSWORD); properties.setPropertyValue("usessl", false);
newInstance()method of the
ConnectorFacadeFactoryto create a new instance of the connector.
ConnectorFacade conn = ConnectorFacadeFactory.getInstance() .newInstance(apiConfig);
Validate that you have set up the connector configuration correctly.
Use the new connector with the supported operations (described in the following sections).
