Well I'd firstly work out what functionality is in the server side of
the system and what is in the client side. You may be able to use parts
of the server-side code by plugging it into the J2EE model.
Secondly, you can start to think about the client-side functionality and
how this can be ported to a server-side context also.
The UI needs some consideration too, and it's worth really spending some
time here, working out if the existing system really does what the users
want. You may find that simply replicating the UI is not the best
approach. The process of porting the application means you have a
certain amount of work to accomplish anyway, so why not make sure you
dont head down the wrong path at the outset.
You need to look at how much you can reuse, how much needs to be
refactored and how much needs to be scrapped and re-written. It's useful
if you have a model of the system to work from and there are many CASE
tools available to drive a model from the existing application.
Approaches:
1) Decompose the system
2) Build a domain model
2) Research any issues with the existing approach, and design "better
ways"
4) Categorise into; "reuse", "refactor" and "re-write" chunks.
5) Start work on your new web approach model
6) Extract resuseable components and sanity check the code
7) Refactor code and add to your model
8) Fill in blanks by writing new code to fit the new model.
It's just a start, but you can see how the approach could be. Just take
it slowly, and take it one step at a time.
Visual models are good, long verbose documents are bad. ;-)
