You can use the NMR to pass messages between Camel routes and/or between Camel applications.
In the same Camel application you can also pass messages using the direct component, but that only works within the same application.
For webservice CXF is just regular SOAP-WS. You can find books about it, documentation at Apache CXF and at FuseSource
And there should be some CXF examples in the FUSE ESB distribution kit.
Thank you very much. I am gonna try this standalone version of the webservices and try to understand how I can get it to work.
