Apache Cocoon

Hi Every body
I recently started looking for Apache Cocoon and started learning about it
it looks very interesting framework that as I learned so far is based on spring framework and uses the pipeline SAX processing method to process xml decuments into different formats to be used on the web
I think the most interesting this about cocoon will be the xslt transformation and how easy it can provide it
also the variety of formats and the big community for support wil make it an interesting product to use

I'll keep reading and update the topic about anything new or interesting.

Cocoon uses the pipeline to create static and dynamic resources on your web site from xml input using 3 components
1- Generator (Like XMl and File Generators)
the generator is responsible for reading the input for Cocoon
2- Transformer
an examle of the transformer is the XSLT transformer
transformers transform the xml generated from the negerator to generate the output
3- Serializer
the serializer writes the generated transformed output to the client

Cocoon uses a method called sitemap where it defines certain patterns for the resources that the client is going to be generated by cocoon and the generator, transformer and serializer for this resource following is an exmaple fo the sitemap definition and it is an xml file


this sitemap tells cocoon that to listen for requests for hello.pdf and to use docs/samples/hello-page.xml as the input file and use the stylesheets/page/simple-page2fo.xsl file to transform it and to write it to the client using FOP as PDF file

This makes the developement of web resources quite easy
