[axis2] Advice on how to tell which version of WSDL the client is using.

[Bo Xie]

Hi all,

  I need some advice on handling client using old WSDL. Say I made some
change in WSDL and publish a updated service.
  - How can we tell if the client request is based on the old WSDL or new
WSDL so the service can act accordingly?
  - What's the best practice to deal the client that is still using the old
WSDL in case the new WSDL is or is not compatible with the old one?

  Thanks in advance for your time.
