Lars,
Thank you for your response. Sorry if I was unclear, however, your
response did help me understand somethings better. I have some
additional issues I'd like to ask your help with...I'll be much more
verbose.
You did understand my question correctly: I want my servlet/jsp Tomcat
web app to "call" Cocoon to perform presentation layer rendering. I
also don't want to have to create a sitemap that encompasses my entire
(existing) application just to utilize Cocoon's rendering abilities on
these few pages; I only want to use cocoon on a page-by-page basis.
Specifically, when I want to render a tabular report I would like to
have jsp generate do the data-lookup, create the XML and pipe that to
the cocoon engine, which will then transform the document into xhtml.
First of all, is there another way to communicate with cocoon rather
than going through the Cocoon servlet? In other words, it sounds as if
I can only use the http protocol to communicate with cocoon: the
client request first travels through my servlet, which makes requests
to cocoon servlet, which matches the URI pattern and does the
appropriate processing, which returns the output back to my servlet
who kindly renders it to the client. If this is correct, is there
another way to do this? (I can do a URL.getContent() or something for
testing but I don't know if my architects will approve of this).
I don't know of any other way to get Cocoon to do this, other than using
HTTP. But I'm not an expert.
Here's some background info:
I'm developing on a win2k box and my application lives in
$CATALINA_HOME/webapps/. In contrast to Cocoon's default directory
structure, that of my application is as follows:
/src
/web
/web/WEB-INF/
/web/WEB-INF/classes
/web/WEB-INF/data
/web/WEB-INF/lib
/work
I understand about modifying server.xml to point to cocoon's home,
currently accessed by visting http://localhost, context element is set to:
Similarly, in the $CATALINA_HOME/conf/server.xml file myApp context is
set to:
So, after your response I did a little more digging around and found a
reference within "C:cocoon-2.1.7buildwebappsitemap.xmap" to a
mount-table.xml file (below):
Within this mount-table.xml file, I should then add:
Which should delegate processing instructions to myApp's subsitemap
(c:/eclipse/workspace/myApp/sitemap.xmap). myApp is accessible at
http://localhost/myApp/ - since the context is set in the server.xml
file - but apparently its not processing the subsitemap file.
I'm attempting now to get access call the cocoon pipeline now and
would love to get your feedback/insight into the above, I'd greatly
appreciate it. I'm suffering under a pretty heavy proof-of-concept
deadline!
Again, thank you.
Jason
I had trouble reading the XML in your message because it was embedded in
HTML and not escaped, so it basically disappeared.
But here's where I think the confusion is: "myApp" is your servlet (jsp
Tomcat webapp) which is supposed to call Cocoon. Cocoon should then
process requests using your Cocoon code, which we'll call
"myCocoonBlock" to avoid confusing it with "myApp". [In my previous
email I called it "myCocoonRendererApp".]
Your mount-table.xml file needs to have a src="..." pointing to
myCocoonBlock, not myApp. When myApp calls Cocoon, it uses a URL
"/myCocoonBlock/..." The mount-table should have
<mount uri-prefix="myCocoonBlock/" src="path-to-myCocoonBlock" />
HTH,
Lars
