The submission version specified an outdated version of WS-Addressing, using the http://schemas.xmlsoap.org/ws/2004/08/addressing namespace, which has since been replaced by the official http://www.w3.org/2005/08/addressing
namespace. Most other web services implementations supporting the submission version of WS-ReliableMessaging have deviated from the specification by moving to the official WS-Addressing release with the http://www.w3.org/2005/08/addressing namespace. CXF supports the submission version of RM with either WS-Addressing namespace.
For compatibility with older versions of CXF, the default is to use the February 2005 submission version of RM with the submission version of WS-Addressing. On the client side, you can configure CXF for whichever version of WS-ReliableMessaging you want to use (see Reliable Messaging Configuration Guide, along with the Runtime control properties below). On the provider side, CXF adapts to whichever version of WS-ReliableMessaging is used by the client and responds appropriately.

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.RMCaptureInInterceptor | Caching incoming messages for later retransmissionpersistent storage. |
org.apache.cxf.ws.rm.RMDeliveryInterceptor | Assuring InOrder delivery of messages to the application. |
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. |

Key | Value |

WSRM_VERSION_PROPERTY | String WS-RM version namespace (http://schemas.xmlsoap.org/ws/2005/02/rm/ ![]() or http://docs.oasis-open.org/ws-rx/wsrm/200702 ![]() ) |
WSRM_WSA_VERSION_PROPERTY | String WS-Addressing version namespace (http://schemas.xmlsoap.org/ws/2004/08/addressing ![]() or http://www.w3.org/2005/08/addressing ![]() ) - this property is ignored unless you're using the http://schemas.xmlsoap.org/ws/2005/02/rm/ ![]() RM namespace) |
WSRM_LAST_MESSAGE_PROPERTY | Boolean value TRUE to tell the RM code that the last message is being sent, allowing the code to close the RM sequence and release resources (as of the 3.0.0 version of CXF the RM code will by default close the RM sequence when you close your client; earlier versions of CXF did not close the sequence unless told to using this flag, or if configured with a source policy <wsrm-mgr:sequenceTerminationPolicy terminateOnShutdown="true"/>) |
WSRM_INACTIVITY_TIMEOUT_PROPERTY | Long inactivity timeout in milliseconds |
WSRM_RETRANSMISSION_INTERVAL_PROPERTY | Long base retransmission interval in milliseconds |
WSRM_EXPONENTIAL_BACKOFF_PROPERTY | Boolean exponential backoff flag |
WSRM_ACKNOWLEDGEMENT_INTERVAL_PROPERTY | Long acknowledgement interval in milliseconds |
You can also monitor and control many aspects of RM using the JMX + Management features of CXF. The full list of JMX operations is defined by org.apache.cxf.ws.rm.ManagedRMManager and org.apache.cxf.ws.rm.ManagedRMEndpoint, but these operations include viewing the current RM state down to the individual message level. You can also use JXM to close and/or terminate an RM sequence, and to receive notification of when previously-sent messages are acknowledged by the remote RM endpoint.
For example, if you have the JMX server enabled in your client configuration you could use this code to track the last acknowledgement number received:

private static class AcknowledgementListener implements NotificationListener { private volatile long lastAcknowledgement; @Override public void handleNotification(Notification notification, Object handback) { if (notification instanceof AcknowledgementNotification) { AcknowledgementNotification ack = (AcknowledgementNotification)notification; lastAcknowledgement = ack.getMessageNumber(); } } // initialize client ... // attach to JMX bean for notifications // NOTE: you must have sent at least one message to initialize RM before executing this code Endpoint ep = ClientProxy.getClient(client).getEndpoint(); InstrumentationManager im = bus.getExtension(InstrumentationManager.class); MBeanServer mbs = im.getMBeanServer(); RMManager clientManager = bus.getExtension(RMManager.class); ObjectName name = RMUtils.getManagedObjectName(clientManager, ep); System.out.println("Looking for endpoint name " + name); AcknowledgementListener listener = new AcknowledgementListener(); mbs.addNotificationListener(name, listener, null, null); // send messages using RM with acknowledgement status reported to listener ... |
