I should have spotted this earlier sorry, are you not clear on how to 
construct a java web application?  Lots of stuff around (Google is your 
friend) to explain how to make a basic web app, a Comet app is a special 
case of this.



This mailing list is better at answering specific questions, or solving 
specific problems, rather than providing extended starter tutorials.


If you have a specific problem it will be easier to assist.

I would like directions or steps on how to set up a working Comet test
example. I'm very new to Comet and haven't been able to find a

step-by-step

process as to how a Comet application is set up using a servlet with

Tomcat.

I want something like:

1. Change the Nio connector. Find the file.....and change....etc.
2. Place this Java servlet code in the .... directory....etc.
3. Place this jsp code....in the .... directory....etc.
...



Ditch the idea of using JSP completely, you won't be able to, as 
Matthias said below.  Comet servlets need to implement the 
org.apache.catalina.CometProcessor interface, a compiled JSP will not 
have this. (See http://tomcat.apache.org/tomcat-6.0-doc/aio.html).


The page above has example code.

Every example I try seems not to work and I want to make sure that I'm
following the proper steps and not leaving anything out.

I think you need to explain a little more on what you want to achieve by
using comet with JSPs.

The JSP processing model is bound to the traditional Servlet processing

model, 
and a compiled JSP is a traditional Servlet - not a Comet Servlet.

I am not sure if including response snippets generated by a JSP into the
response stream via a call to RequestDispatcher.include would work.

Matthias

Ok. But how is it all suppose to be put together? I want to use comet
using
jsp, but I don't see any jsp code.

This post
(http://www.nabble.com/comet-questions-td14673697.html#a14673697)
contains test code for both a client & comet servlet.  See if it
helps.

To anyone who has successfully used Comet:



I've been trying to use Comet with Tomcat 6.0 for a few weeks now and

have

been unsuccessful. I'm so frustrated with the lack of documentation

and
the

unusable example that was given with Tomcat.



Are there any step-by-step instructions on how to successfully

implement a

test program?
