Message Exchange

A request message and its corresponding reply or exception message is represented in Camel using the Exchange interface. This interface provides an abstraction for this pattern of communication between systems. The presence of a reply message is optional and depends on the exchange pattern used in the integration. Thanks to this, Apache Camel can support different integration patterns such as:

• Event Messages: messages that have only an inbound message
• Request and Reply: messages that have an inbound and an outbound message.
