Newbie questions
Hi all,
I'm a complete newbie with Cocoon, so please excuse me if I ask rather dumb
questions.
I have managed to install Cocoon without any problems (that I can see). I
have a couple of questions:
1. I would like to be able to offer it to a couple of virtual hosts on my
server and was wondering what was the best method. Reading the archives
I've seen a couple of methods, but can't see which would be the most
effective in terms of resources etc.,
An example configuration file for 'morons' like me would be very helpful
2. I can run the example applications etc., that come with the
installation. I'd like to be able to conduct a very simple test for the
virtual hosts. Does anybody know of a very simple way of doing this? Even a
really simple application. I just need to see whether the configuration for
virtual hosts is correct or not. (see above). I did a search on Google, but
the only simple example I came across will work even without Cocoon
installed! (It was an old example)

How to translate?
Posted by Albert Cervera Areny <in...@sedifa.com>.
Hi,
I've been looking at the i18n transformer in the documentation web page,
however I can't see how it works in production. I got the idea that it
works let's say like gettext as you mark which parts you want to translate
and generate a file with those messages.... if so... how can I do that
easily? I've been looking throw those convert and merge xsl files but they
don't seem to generate it. I was able to create a file to translate into
one new language from the simple_dict.xml example but how may I create it
from scratch?
These two files, messages and dictionary, are the ones that make me not to
understand the hole process.
Could someone clarify those aspects or point me to a better resource?
Thanks in advance!

I don't believe there is (although I'm not 100% sure -- I'm still investigating
this area), so I should qualify my statements about multiple users sharing
a single instance to say that they're also sharing the same versions of
the same classes.
So this configuration is probably of most interest to people putting together
applications (i.e. sitemap configuration, XSLT transforms, etc) rather than
application development.
I've amended my article, which is now in the CocoDocoWiki:
http://outerthought.net/wiki/Wiki.jsp?page=UnderstandingCocoonMounts

Hi
I´ve got a question concering 'multiple users sharing a single cocoon
instance'...
We can seperate the workspaces and sitemaps of all users with a subsitemap
mounting.... but how can i keep the libs and classes seperated (without
enforcing a pre-package name like our.customer.classes.*) ?
So... is there a way to say to cocoon (or to tomcat)... "there, there and
there are libs/classes you have to search for at each reload of the

What MUST be included in such cocoon.xconf file ?
Is it enough:
<cocoon version="2.0">
<datasources>
<jdbc name="foo><!-- datasource definition here --></jdbc>
</datasources>
</cocoon>
and that is all ? Furthermore: Is it possible to omit the jdbc driver preload

Here's a document that I've been working on which should help you
ought with how to do sub-sitemaps. The additional configuration steps
will be to use the Host selector -- I believe there's an example of
this already in the Cocoon docs.
If anyone has any feedback on the following please let me know, it
was quickly drafted on a train journey so hasn't been thoroughly
proof-read. (Also forgive the scraps of Wiki markup, it's extracted
from my personal wiki site, and the cross-posting -- hoping
for sanity checks from the developers also)
btw, was a separate mailing list for Cocoon documentation ever
created? IIRC there as a proposal to do so recently?
-------------------------------------------------------------------
!!Understanding Cocoon Mounts
!The Root Sitemap
The default Cocoon web application reads the sitemap.xmap file
in the $webapp_home directory for instructions about how to
process incoming requests.
This means that if the Cocoon web application is installed in
$TOMCAT_HOME/cocoon
Then all requests with the base URL of:
http://localhost:8080/cocoon/...
will be serviced by asking this sitemap for a suitable pipeline.
The matchers defined in that sitemap can allow for arbitrary
amounts of additional path information, but it is this initial
root 'mount point' that determines basic request processing.
So for example a pipeline with:
<map:match pattern="my/long/url/path/*.html"/>
Will match:
http://localhost:8080/cocoon/my/long/url/path/doc.html
So while the Cocoon web application is mounted at /cocoon
in the servlet container. The pipelines are mounted from
/cocoon/
However placing all pipeline and component configurations in
a single sitemap can be unwieldy, it's better to partition up the
web application. This can be done by creating additional sitemaps
which contain related functionality. E.g. all form processing
relating to registration, searching, etc.
!Mounting Sub-Sitemaps
Partitioning a sitemap in this way involves use of the <map:mount/>
element. This indicates that a second sitemap should be processed,
and includes the location of that sitemap.
E.g.
<map:match pattern="my/long/url/path/*.html">
<map:mount src="my/long/dir/structure/sitemap.xmap"/>
</map:match>
Will cause the sitemap in $TOMCAT_HOME/cocoon/my/long/dir/structure/
to be queried for pipelines that can process this request. The second
sitemap is referred to as a ''sub-sitemap''. It inherits all component
declarations from it's parent, so there is no need for them to be redeclared.
However the empty container elements (e.g. <map:generators/>) must
still be provided for the sitemap to be parsed correctly. These elements
can indicate the name of the default component as usual.
However, any matchers in this sitemap would still have to
use the full request path for their match to work as expected
I couldn't do:
<map:match pattern="*.html"/>
As this actually matches
http://localhost:8080/cocoon/*.html.
To enable additional unwanted path information to be ignored,
we need to add an additional uri-prefix attribute to the <map:mount>
element, as follows:
<map:match pattern="my/long/url/path/*.html">
<map:mount src="my/long/dir/structure/sitemap.xmap"
uri-prefix="my/long/url/path/"/>
</map:match>
Which means that a matcher with the pattern *.html in
$TOMCAT_HOME/cocoon/my/long/dir/structure/sitemap.xmap will
match:
http://localhost:8080/cocoon/my/long/url/path/doc.html
but not
http://localhost:8080/cocoon/*.html
The other additional parameter to the mount element is check-reload
which can have the value yes or no. This indicates whether the mounted
sitemap should be reloaded if it changes.
!Location Independence
Note also that the sitemap location is completely separate to the
path info in the URL. I can maintain my sitemap.xmap file anywhere
on the file system that can be read by Cocoon. As is usual in Cocoon
pipelines, it's the matching components that dictate how a request
path is tied to a sequence of processing.
!Partitioning Options
The above example have assumed that the Cocoon application has
been partitioned into a collection of sub-sitemaps according to
the request path.
However it's perfectly acceptable to partition an application based
on any criteria. In fact any selector or matcher component can be
used as the means to delegate processing to a sub-sitemap.
So, for example I could use the HostSelector to select an alternate
sitemap based on the host name used in the request. Or I could
use the BrowserSelector to separate processing based on user-agents.
The ParameterMatcher could select sub-sitemaps based on request
parameters, and so on.
!Auto-Mounting
Extending this facility to its natural conclusion, we can use the
power of the WildcardMatcher component and the <map:mount/>
element to create an 'auto-mount' feature that will allow sitemaps
underneath a given directory structure to be automatically loaded
by Cocoon.
We can achieve this with the following:
<map:match pattern="auto/*/**">
<map:mount uri-prefix="auto/{1} src="auto/{1}"/>
</map:match>
This uses wildcard, and sitemap parameters to automatically match
a base request url, in this case:
http://localhost:8080/cocoon/auto/...
The first path element is matched and stored in {1}. This is
then used as the name of the directory from which to load
the sitemap. In this case a request for
http://localhost:8080/cocoon/auto/foo/bar.html
Will cause the sitemap in:
$TOMCAT_HOME/cocoon/auto/foo
to be loaded and the prefix /auto/foo/ automatically
stripped.
Auto-mounting can use the flexibility required earlier to auto-mount
sitemaps based on request parameters, and a whole range of
other options. However doing so using a correlated request-path
and directory structure makes the functionality more intuitive.
!Auto-Mounting and Users
Auto-mounting is a good way to allow multiple users to share a
Cocoon instance. Their public_html directories can be symbolically
linked to the 'auto' directory, and they can then operated independently
of one another.
!Sub-Sitemaps and Components
Since Cocoon 2.0.X it has been possible to include additional cocoon.xconf
files in sub-directories. These will be automatically processed by Cocoon,
allowing the declaration and use of additional components, JDBC connections,
etc. Again this enables multiple users to more easily share a single
Cocoon instance.
It also provides a fairly clean way to package a Cocoon application for
sharing with others: create a directory complete with sitemap.xmap, cocoon.xconf
if required, and all additional supporting files. This package can then be passed
on to others who can install it by simply unpacking it into their file-system
and adding the appropriate mount elements into their root sitemap (or one of
it's sub-sitemaps).
In this way, a service provider can also choose to host Cocoon applications
for others.

There are couple of ways:
1. Have single Cocoon instance serving requests to all virtual hosts.
Use host matchers/selectors to select resource to serve.
2. Have single Cocoon instance with sub-sitemap for every host. Put
apache in front of Cocoon with rewrite module.
Sorry, don't have configuration examples - didn't had need for multiple
hosts.
