Purpose of message.getId? Returning null in CXF

[cj91 <Jo...@argushealth.com>]

In some code that we are porting from XFire to CXF:
externalSessionId = soapMessage.getId();

In XFire, it seems this used to return a session identifier. We use this in
a custom interceptor to match different bits of tracking data together since
they belong to same invocation.

We're port the xfire handler to a cxf interceptor, but it seems that we are
getting a null String from cxf on this method. Should we be using it for
this purpose? Is there something that CXF generates (like a sessionid... I
know I know webservices are stateless) that we could use to identify a
specific invocation of our services?

Many thanks, and thank you for hard work on this project. I can't imagine
implementing webservices any other way!

Interesting.   I just checked the entire codebase and there are not ANY calls 
to Message.getId or Message.setId.   Thus, I would say they are "left over" 
bits from the XFire migration that probably either shouldn't be there, or 
should be implemented.   Not sure which really.  :-)

Usually what you do is generate your own ID of some sort and do something 
like:
message.getExchange().put("My.Key.Identifier", key);
that you can then get later to correlate.
