I don't know about anyone else, but I would say at least a few weeks, plus
time to learn JSP, Servlets, etc. One discussion myself, Craig, Daniel and
a few others have been continuously going on about is the Model 2
architecture. So that Craig and Daniel don't have to repeat themselves, we
started this about 3 or 4 weeks ago. Look in the archive list for any
subject stating Model 2, JSP Model 2, etc. I think at least 100 emails have
been passed across this list on this subject in that time. I would try to
dig up all those, print them out and start reading! However, feel free to
ask away too.
The idea is simple though..all incoming form requests go to a single
controller servlet, which deducts the "action" name, loads a class (or gets
it out of a hashtable if its already been created), calls its perform()
method passing to it the request, response and servlet objects, and the
action class is responsible for doing the logic (or creating a bean that
does the logic) and forwarding to a JSP page based on the conditions the
logic does. This sets yourself up for easy conversion. The HTML in the ASP
pages should be directly workable in JSP pages. The JSP pages are your VIEW
only, the controller servlet is the CONTROLLER and the JavaBean the action
class creates that the JSP VIEW page uses to display dynamic content becomes
your MODEL..and possibly your CONTROLLER as well (if you put logic in it).
There is alot on this topic..but Craig and Daniel have provided this list
with ample amounts of good knowledge and have paved the road for me and at
least a dozen others following and responding to the discussion to implement
a good sound Model 2 architecture.
I don't know the amount of code and all that you have, but converting 43
pages with 25 procedures I would estimate at about 1 to 2 months,
again..depending on the nature and size of the project. Keep in mind the
learning curve for Java (not that steep if you don't know it well) and
learning the whole Model 2 architecture setup..which is actually extremely
easy to do, and you should be set to start in a week or two, maybe a bit
longer.
Hope this helps. Again..feel free to ask me in email, or the list for help.
