Examples of org.apache.servicemix.nmr.api.Message

org.apache.servicemix.nmr.api.Message
The Message represents the content of a request, a response or a fault. Messages are part of {@link Exchange}s are created using {@link Exchange#getIn()}, {@link Exchange#getOut()} and {@link Exchange#getFault()}. If the Exchange has to go to a remote ServiceMix instance to be processed (if the instance is part of a cluster), all headers, attachments and content have to be Serializable.
