Re: [Webware-discuss] Web pages as objects

[Winston W. <st...@ob...>]

Hello Ian-

I like your idea of having one servlet that dispatches requests to a=20
bunch of other objects that are not servlets.  I'm having a little=20
problem though, with getting the request to go to that servlet and not=20=

to the other objects.  That's a little hard to read, let me explain it=20=

with this diagram:
	/MyContext/
		Main.py   (This is my servlet which loads all the files =
below it like=20
One.py, Two.py, etc.)
		One.py	(This object is NOT a servlet, it just has an =
html() method=20
that returns my HTML text.)
		Two.py	(This is another object with just an html() =
method)

The idea is that a request to http://myserver/MyContext/One.py should=20
be received by Main.py, and it will:
	=95 Cut off the extraURLPath, which will be "/One.py"
	=95 Main loads the MyContext.One.One object and calls it's =
.html()=20
method.
	=95 Main writes that text to the response object and returns.

The problem is, how do I get Webware to load and call the Main object=20
as opposed to the One.py object?
