Could someone forward me to a resource that talks more about using
One servlet in Model 2 architecture. I am skeptical about how a large
application can handle all request through one servlet.

Thanks for the response. I guess I should have been more clear. I'm not
concerned about a performance impact. As you say, it should not be an issue.
I *am* concerned about code complexity, manageability, and maintainability
with as many forms as I have.

I don't see that using the model 2 type architecture will have any negative
impact
on the speed of your application.
Just because all requests are being channelled through one servlet (the
dispatcher)
does not imply any any performance degradation compared to, say, calling the
jsp
files directly.
This is assuming the dispatcher has been written correctly - the main thing
to bear
in mind is that your dispatcher must not be a thread bottleneck - this is
ensured
by not storing any state between requests in your dispatcher - ie everything
should
be on the stack.
