Code Q.
Hello,
I am learning JSP and have done quite a few examples from the Core Servlets
and JSP book.
I apologize for asking this q here, but I am trying to learn Tomcat and put
my whole picture together, and I figured that
the people on this line, would probably know what these lines mean.
Anyway, I keep typing these few lines but really don't have a grasp of what
they are doing.
I would really like to understand in a 'Laymans' fashion what I am doing and
what these lines do.
public class Hello extends HttpServlet {
//I am assuming that the class Hello, that I am creating
// is extending HttpServlet class?
// but what does the extends really mean?
public void doGet(HttpServlet request,
HttpServlet response)
throws ServletException, IOExcedption;
// It looks like I am creating? or calling? a method here. And am I passing
it the HttpServlet class?
I am very confused on this, and would enjoy hearing from someone that
wouldn't mind going over that with me.
Thanks very much,
Sincerely
Scott

You kight want to get some decent example code,then edit that to get you
started. If you have either of the O'Reilly books (servlet programming or
JSP) then download thier example code. The JSP code certainly works just by
unpacking under tomcat. You can then just edit/view thier simple examples to
start getting to know it.
For basic Java tutorial, Bruce Eckels has an online book called Thinking In
Java - which you can download for free.

Hello,
There are many good books on java basics. I personally like the Core Java 2
series. Start with volume 1 of course. Getting comfortable with object
oriented programming is essential to developing an understanding of how java
is used. I also highly recommend visiting www.javaranch.com which is a very
friendly place. :0) Make sure to read "how I taught my dog polymorphism"
and visit the saloon regularly.
Good luck,
Craig

One thing that the Core Servlets book doesn't do well is explain Java
basics, like what does extends mean or how do method/class declarations
work. It assumes that knowledge. I found Sams "Teach Yourself Java in 21
Days" really helpful; it contains a lot of basic java information that would
address your questions pretty well.
You might want to look at the webapps\examples\web-inf\classes directory of
tomcat for some good basic examples of what servlets look like.
