About Connect JCA rules |
New | Service | Input | Output | History | More |
Use JCA connector rules to connect your application to an external Enterprise Information System (EIS) through a resource adapter that implements the Common Client Interface (CCI) of the J2EE Connector Architecture (JCA) specification. C-1921
Before you begin, create an instance of the Data-Admin-Connect-JCAAdapter class that defines the resource adapter you want the connector to communicate with. See More about Connect JCA rules.
A JCA connector rule gathers the data for an input record and then
invokes the resource adapter Execute()
method for a specific
function. The resource adapter data instance specifies which
Execute()
method to use. The connector rule determines which
of the resource adapter InteractionSpec
methods to use and
provides the input record object. If required by the resource adapter,
the connector rule also instantiates the output record object and
provides a reference to that object in the request.
Use the Connect-JCA method in an activity to begin execution of a Connect JCA rule.
To debug your application, you can simulate a JCA connector when the external class is unavailable or lacks a test environment. See Creating Connector Simulations.
Connect JCA rules belong to the Integration-Connectors category. A Connect JCA rule is an instance of the Rule-Connect-JCA rule type.
