I read about flow before and in fact I intended ot use
it once I got this supposedly "basic" part of the site
resolved.
Anyway, I re-read the documentation and I can't seem
to find out how it would help the situation described
below. How can I use flow logic combine 5 pages that
require dynamic processing into one page?
There are several ways to do this. Take a look at the docs for:
aggregating (sitemap element), cinclude or xinclude (transformers).
I'll give a small example:
- Let each request go through one sitemap matcher
- This matcher has either an aggregate:
<map:aggregate ... maybe defining a new surrouning parent element
<map:part.... here your different parts (menu/content/sidebars...)
or read in a template page and use includes:
<map:generate src="template.xml"/> (template contains include tags
for each different part)
<map:transform type="cinclude"/> (this step reads the include tags
and calls the different pipes to include)
- each part for menu/sidebars/... can be processed by separate matchers
in an internal-only pipeline
- each matcher can contain its own flowscript functions if needed(thus
program/call anything you like), or you can produce general information
in your template sitemap matcher (eg by action , own component or again
flowscript, doesn't matter) and set these in your session or context so
it's available within the different parts.
- the template matcher will then contain all the information and you can
style this to any outputtype you want (probably just plain html). Just
remember to leave your html styling and javascript in different files
and include these.
When creating your own generator/components remember to make these
reusable and that there is already a lot of funcionality available.
Kind regards,

I'm converting my site from pure JSP to Cocoon.
I've read lots of tutorials on Cocoon and I've come
really close to getting the site to work the way I
want but I've hit a few snags.
Basically, the site has a header, footer and two
sidebars with content in the middle. In JSP, I
would
just have includes on every page for the header,
footer, etc. However, in Cocoon, I was hoping I
could
have one "template" page that decided the layout.
I was able to create this model, mainly using this
tutorial:
http://www.cocooncenter.org/articles/navigation.html
I created an XSL stylesheet for the header, footer,
and two sidebars, along with associated XML content
files and imported those into a "main" stylesheet.
Then, in the main stylesheet, I apply the templates
for the constant parts by using the document
function
in XSL, for ex:
<xsl:apply-templates
select="document('..\menus\header.xml')/*"/>
For the main content on each page, I have separate
XML
files that, for now, are simply a dump of static
HTML
and I use the copy-of XSL tag to insert it into the
page. Later, I'll make these XSP pages and
dynamically generate the content.
Here's where I've hit a couple issues. The header,
footer and sidebars contain some dynamic content.
For
example, if a person is logged in, the header will
show something different. I was able to get around
this by passing in the "remoteUser" parameter to
the
stylesheet in the pipeline and then using
stylesheet
logic. But, there's also other logic I will need
to
process that's a bit more complicated (ex.
depending
on the user's role, etc). With my current layout,
I
can't seem to find a way to add logic that can use
Java to these mostly static blocks.
I've tried aggregating, but that doesn't seem to
work
well with XSP. Also, I'd like to not use cinclude
since I'd like to avoid including the other
elements
on every page like in JSP.
Might anyone have any suggestions for me out there?
Thanks a ton.
