Hi Cocoon devs,
I wonder if the servlet service framework can be used to implement the
following scenario:
There is an "abstract" block called "document-type" (think of a document
type for a CMS, actually it's about Lenya). This block declares (in the
sense of a convention) particular services, without actually
implementing them, e.g.
/services/schema.rng (provide Relax NG schema for validation)
Other generic blocks operate on arbitrary document types. E.g., the
"editor" block could invoke a validation step before a document is
saved. Now I imagine something like this in the editor block sitemap:
<!-- {1} is the block name of the actual document type -->
<map:match pattern="schema/{*}">
<map:read src="servlet:{1}:/services/schema.rng"/>
</map:match>
I guess this works if the block servlet declaration of the editor block
contains connections to all actual document type blocks (extending the
"document-type" block) that exist in the application. But since the CMS
should be easily extensible with new document types, I think we can't
require to register each document type with each generic block that
operates on document types.
Does it make sense at all to implement such a scenario using the servlet
service framework? If yes, is there a way to achieve this behaviour
using the current implementation? Could I just register the service
connections programmatically (e.g., using a standard init-method of a
bean in the actual document type blocks)?
Thanks a lot in advance for any comments!
BTW, sorry for posting this to the dev list, but actually I'm afraid the
current SSF doesn't support this, and I'd be interested in your opinions
if this concept should be supported at all.
