Cocoon 2.1.11 in Tomcat 7.0.12: cocoon welcome page will not display
I am trying to learn about servlets, java server pages, web-apps etc.
I am new to this world, but I am an experienced programmer (though not
in Java).
I have built the cocoon.war file in the prescribed manner and have
tomcat installed.
I have copied the cocoon.war file into the webapps directory, and when
tomcat
start it successfully unpacks the .war and creates the cocoon directory
structure.
Every web page that I have read says that this is all that is required
to deploy cocoon
under tomcat.
However, when I browse to the cocoon welcome page:
localhost:8080/cocoon
I get a fault and a java stack trace that I include at the end of the email.
Browsing to localhost:8080/cocoon/welcome gives a similar result.
The gist appears to be that it is looking for an "index.html" file.
I have run cocoon successfully standalone (port 8888 etc) and everything
looks fine.
I am only trying to deploy cocoon in a servlet container as an exercise
to improve
my understanding: evidently that understand is much in need of improvement.
I must be doing something wrong that is very basic but I don't know what.
Can someone please give me some pointers as to what may be wrong.
I am running under Linux: Ubuntu Lucid.
Thanks
Rob Stevens

Chris
Thank you for taking the time to respond to my email.
I am sure it must take quite a bit of your time and I am most grateful.
I cannot find a web.xml file in META-INF, but here is what I see in
the <servlet-mapping> sections in
<tomcat-top-level>/webapps/cocoon/WEB-INF/web.xml
(should there be such a file in META-INF? I see only INDEX.LIST and
MANIFEST.MF)
As you said, it seems as though something is missing
(BTW: I am using the book "Cocoon: Building XML Applications"
by Langham & Ziegler. It is very out-of-date and that is probably part
of my trouble.
There don't appear to be many up-to-the-minute books around)
Thx
Rob Stevens

You should be ready to go at this point.

Unless it's been given any other instructions, Tomcat's DefaultServlet
will change anything that looks like a directory into <directory>/ and
then use the "welcome file" configuration (defaults to index.jsp,
index.html).

Cocoon always runs in a servlet container, it's just that you can also
build it so that it runs in one supplied by the good people over at the
Cocoon project. Their build procedure seems geared toward building a
self-container Cocoon "program" that looks like it's standalone but it
actually a servlet container (probably Tomcat or Jetty) wrapped around
Cocoon.
I myself run Cocoon (under TC 6) and have never bothered to run their
included container. I should be able to help.

Okay, so the good news is that Cocoon has been loaded and it responding
to requests. The only question is why it is looking for "index.html". I
suspect that something hasn't been matched properly /before/ this point,
and Tomcat's DefaultServlet is doing some redirecting and/or searching
for a welcome-file.
It would be good if you could provide the portion of your Cocoon's
META-INF/web.xml file that contains the <servlet-mapping> sections. I
suspect that localhost:8080/cocoon or localhost:8080/cocoon/welcome
isn't properly mapped to the Cocoon servlet.
