Could you just use your working cocoon application as a web-service?
e.g. Use commons http to call it? Nice scalability implications...

Hi All,
Hi,
I am new to Cocoon. We are planning to use Cocoon for report
generation (XML
+ excel template passed through Cocoon = Excel file with values
filled in).
I am able to generate the report when I deploy the cocoon as a web
app.
Now the issue is, I want to integrate cocoon into my existing
webapp. By
integrating I mean, I should use the web.xml of my current web
application
and not the one from cocoon. i.e. every request should go through
my old
web.xml.
and when I say generate report, it should invoke methods from
Cocoon and
generate reports.
For ex. I want to have a method like : public Object generateReport
(String
xlsPath, String excelTemplatePath) and this method should invoke
classes
from Cocoon, generate report and return the report.
Please let me if this is possible. Also please direct me to some
documents,
links on this.
I am strictly speaking about Cocoon 3.0 here:
Yes this is entirely possible. Actually it was one of the goals when
designing the new version.
And there are people who did exactly what you described above
(having a web application and using Cocoon inside it, just like you
would use a templating engine or an O/R-Mapper)
However there's a catch: It is still an alpha version.
So the basic question is: can you live with an alpha version?
If the answer is NO, then Cocoon 3.0 is not what you want - you
might as well stop reading this now (I think it will be months
before this goes into any king of beta phase).
If the answer is YES, then Cocoon 3.0 can probably solve a lot of
your problems rather easily.
The basic principles are the same as those of Cocoon 2.x and it's
rather easy to create new pipeline components or modify behaviour
the way you want/need.
("Our" students from the TU Vienna do it all the time, even if it's
not part of their project - apparently they think it's fun)
Cocoon 3.0 provides an API to create pipelines programmatically and
use them basically everywhere you have Java available.
You can even use the sitemap on top of that if you want to and still
use Coccon inside your own application like any other non-web
framework.
The system is already used in some commercial applications and
AFAIK, Apache Sling is looking at integrating it too. (Again it's
the pipeline API that makes certain things possible and interesting).
We are continuously working on it, although this may not be very
visible or prominent at times.
Documentation is another weak point right now. So there isn't much
to point you to.
The general idea about Cocoon 3.0 is sketched out here: http://cocoon.apache.org/3.0/
and a (slightly) more detailed overview is ready here http://cocoon.apache.org/3.0/features.html
.
The documentation is for version 3.0.0-alpha-1.
The current trunk contains a lot of changes and extensions and
thanks to the feedback we got, this version is more consistent,
easier to use, and more reliable.
IMO a new release should follow rather shortly (1 - 2 months) but
maybe I'm a bit optimistic on that.
I am not sure whether this is possible at all with Cocoon 2.x.
I guess some of the "older" guys have to answer that.
I hope this makes sense to you.
Cheers,
Steven
thank you in advance.
