Introduction to Native Connectors

A native connector is a special kind of service that manages requests from CASP applications to native (that is, non CASP-enabled) applications, as well as requests from native applications to CASP applications. When a native connector is used, CASP clients can:

Native clients can participate in CASP N-tier routing by using a native connector. The native client puts a message on the queue associated with the native connector; the native connector can then communicate with one or more CASP business services.

For step-by-step procedures for configuring native connectors, refer to the CASP Administrator Directory Services User's Guide. These helps provide conceptual information about the native connector as well as detailed information on the CASP Administrator dialogs and fields.

How a Native Connector Works

A native connector comprises three business service sets (a business service that contains a business component and business element of the same name) and an internal client, which the CASP Directory Administrator automatically generates for you when you create a native connector. Two of these business services sets and the internal client are shown in Figure 1 below.

Figure 1. A Native Connector in an CASP Workflow

The Native Connector BS is the business service to which Client Appl makes a request (step 1). This business service comprises three business components, one of which represents a native application (NC BE). When the message arrives at NC BE, (step 2) NC Client, the internal connector client, sends a request to Native Server BS, the business service representing the native application (step 3). NC Client waits for a response (shown at step 4) from the native application. This response is sent through the workflow until it arrives at the originating client application, Client Appl (step 6).

These objects are described in more detail in the helps for each tab on the Native Connector dialog.
