Many enterprises use Messaging to integrate multiple, disparate applications.

How can you connect an application to the messaging system so that it can send and receive messages?

Use a Channel Adapter that can access the application's API or data and publish messages on a channel based on this data, and that likewise can receive messages and invoke functionality inside the application.

The adapter acts as a messaging client to the messaging system and invokes applications functions via an application-supplied interface. This way, any application can connect to the messaging system and be integrated with other applications as long as it has a proper Channel Adapter.

The Channel Adapter can connect to different layers of the application's architecture, depending on that architecture and the data the messaging system needs to access.
