CXF supports the February 2005 version of the Web Services Reliable Messaging Protocol (WS-ReliableMessaging) specification. Like most other features in CXF, it is interceptor based. The WS-Reliable Messaging implementation consists of 4 interceptors in total:

Interceptor

Task

org.apache.cxf.ws.rm.RMOutInterceptor

Responsible for sending CreateSequence requests and waiting for their CreateSequenceResponse responses, and and aggregating the sequence properties (id and message number) for an application message.

org.apache.cxf.ws.rm.RMInInterceptor

Intercepting and processing RM protocol messages (these will not the application level), as well as SequenceAcknowledgments piggybacked on application messages.

org.apache.cxf.ws.rm.soap.RMSoapInterceptor

Encoding and decoding the RM headers

org.apache.cxf.ws.rm.soap.RetransmissionInterceptor

Responsible for creating copies of application messages for future resends.
