Hi Jeremy
I'd be interested in working on some variation of BigBank or
maybe a new
sample scenarion that would use a Ajax front end. Do you have any
toughts on
possible scenarios, or areas you would like to exercise in this ajax
sample....otherwise I could think of something...
I have this belief that SCA would make a good platform for building
the server-side handlers for Ajax components. In that mode, the
presentation side is done in the browser and the UI widgets make
calls to the server consuming services just like anything else. This
is a fine-grained, close-coupled service architecture between the
browser and the host server.
A simple scenario to demonstrate this would be to supplement a
traditional JSP UI with one based on Ajax. For example, suppose we
have an application with a set of services that provide its business
logic that get called from server-based UI code (JSP, Struts, Spring,
something) - this would be the traditional (dumb-browser) model. We
then supplement that with an Ajax front-end which replaces the UI
code with client-side JavaScript but leaves *all* the business logic
unchanged. This shows how easy it is to implement this class of
application on top of a service-based architecture.
One way would be to take an application like MyValue, separate the UI
from the services and then add the JS client code.
