The JCA 1.5 enables the EIS to initiate the communication with the application components using the resource adapter. This function is called inbound communication.

The inbound communication involves:

  • Message inflow — using this mechanism, the resource adapter can invoke message-driven beans deployed on the AS Java

  • Transaction inflow — this is the mechanism for propagating transactions from the EIS to the AS Java

Features

Message Inflow

The message inflow enables an external message producer to send messages to a message endpoint on the application server. The inbound resource adapter is the component that enables the endpoint activation, and also defines what type of message listeners are required for the processing of the in-flowed messages.

Transaction Inflow

The transaction inflow contract enables the propagation of a transaction from the EIS to the application server via the resource adapter.
