Ok heres my situation....

I am using NetBeans 4.1 and just doing a simpler than "Hello World" web
app.
I have a web module which has a servlet called "Control1". I have 4
JSPs. There is the "index.jsp" which comes by default and then there
are 3 which I Created. One if called "mainPage.jsp".

Here is what I want to have happen. When someone goes to my webpage,
the servlet "Control1" is called and instantly passes control over to
and displays "mainPage.jsp".

My questions are ...
1) What is the default page used when the URL is invoked?

2) If the default page is not the servlet then how do I set it to be
the servlet "Control1"?

3) How then do I pass on to a JSP to display? This also includes the
question of how do I make the JSP page available/visible to the
servlet?

4) Within "mainPage.jsp" I want to collect info. How do I then pass
this info back to the servlet "Control1"?

I will eventually deploy to the Sun Applicationn Server but right now I
am just working with this within the NetBeans environment.

mainPage.jsp

Just put the servlet up if you're gonna do that and lose the .jsp pages.

You do this with the action attribute of the form element.

<form action="/servlet/path.to.your.servlet" method="get" >
</form>

You can also use method="post". Anything more complicated than that and
you'll have to find someone who knows more than I do.

request.getParameter("textFieldID");

>> My questions are ...
>> 1) What is the default page used when the URL is invoked?

when you want to pass control to some servlet first.. and then to
main.jsp.. you should have some URL like /controlServlet.do and map
this pattern to Controll servlet using web.xml

2) If the default page is not the servlet then how do I set it to be
the servlet "Control1"?
again.. use web.xml and same approach

3) How then do I pass on to a JSP to display? This also includes the
question of how do I make the JSP page available/visible to the
servlet?
you dont have to do anything to make it visible to servlet..
there are various way you can pass the control from servlet to jsp..
response.sendredirect for example

4) Within "mainPage.jsp" I want to collect info. How do I then pass
this info back to the servlet "Control1"?
again.. you will have to call that URL which is mapped to controll
servlet
