Configuring asynchronous cxf endpoint(server) using callback in camel-cxf

Issue

• Could you please provide some sample usecases or documentation to implement asynchronous cxf endpoint with call back in camel ?

• We need to configure a soap web service using cxf endpoint to receive the soap request.

• Client will send the request and do not wait for the response in the same endpoint.
  Client will be sending the reply to address in ws-addressing header.

• At fuse side , the processing will take take some and once the response is ready , the cxfendpoint should respond to the address provided by client in reply to address header.

• How to configure cxf endpoint in spring dsl for call back scenario and need to correlate the responses also ?
