Developers,
I have a website setup in the following manner:
JSP -> Servlets -> Axis WebServices -> Database

The JSP displays the Axis objects that is pulled back via the
Servlet.  The Servlet pulls information via Webservices and uses an
Axis stub to invoke a service and receives Axis objects on the
callback.  The web service does a lookup on the database and generates
the results to return.

I'm trying to integrate GWT into this framework in order to use the
built-in AJAX functionality.  From the documentation that I've read, I
would need to create a separate set of objects for displaying the
information in the JSP and using the Axis objects only in Servlets.

However, I see this as a maintenance nightmare as I would need to keep
two similar objects in-sync instead of passing around the same object
as before.  Is this the recommended approach?  If not, what are my
alternatives?

Also, is there a way to make the updates to these objects a snap?
Like if the WSDL on  this website changes, I can run WSDL2Java and be
ok.

Thanks.
