Hi,
I seek precious advice and knowledge for those who are willing to
share theirs on the above.

I am currently responsible in migrating my client server application
which is written in PowerBuilder to the web. I plan to use the
approach of having the UI(Presentation) and Business Logic separated
whereby the Business Logic should be firstly converted to a NVO
before compiling it as a component within EAServer.

However the challenge is that most of our application is written in
a way whereby the Business logic is being embedded within the UI

eg: THe Business validation process and Data update/retrieve logic
is written in the Window/Visual Object events/functions. This makes
is difficult for me to achieve the idea of having the Business Logic
and Data Logic to a NVO

Is there any tools or approach out there that can do the above?
THanks
Kwan
