About Connect JCA rules

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 Java EE Connector Architecture (JCA) specification.

The following tabs are available on this form:

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.

Where referenced

Use the Connect-JCA method in an activity to begin execution of a Connect JCA rule.


Use the Application Explorer or the Connector Definitions & Simulations landing page to see Connect JCA rules in your application. Use the Records Explorer to list all Connect JCA rules that are available to you.


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.

Where referenced

Connect JCA rules can be referenced in an Integrator shape ( Integrator ) of a flow rule, or on the Definition tab of a Data Page rule, as the source of data for the contents of the data page.


Connect JCA rules belong to the Integration-Connectors category. A Connect JCA rule is an instance of the Rule-Connect-JCA rule type.
