SOAP vs AXIS

I'm starting to write an Java application that is invoked as a simple
command-line app.  The program will invoke a web service to retrieve some
information.  So far, I've been using AXIS for this, but as I read SOAP
docs, it seems I could do the same w/ SOAP.  I have also started to think
(perhaps mistakenly) that AXIS is replacing SOAP.

Is there a document that describes the pros/cons of SOAP vs AXIS?  Should I
continue w/ AXIS or should I be looking at SOAP?

Thanks
