I'm beginning to get just a little bit confused. So far I have a couple
of Cocoon 2 applications that mostly use XSP with ESQL to query a
database. All is running well, but I don't really like the idea of
having pages that depend on the physical structure of the database.
Thus, I started exploring different alternatives and came up with the
idea of having a library of (possibly reusable) Java objects that
represent entities in the database (via EJB or some O-R mapping tool
like Castor or whatever).
The troubles come when I start thinking about how I might feed a (XML)
representation of those objects to Cocoon in order to represent them,
say on a web page. As far as I can see, these are the possible choices:
- call my objects from an XSP page, specifying element names in XSP and
use <xsp:expr>myObject.getSomeField()</xsp:expr> for the values
- like the above, but using a taglib for reusability
- write a Generator
- make my objects implement XMLizable and override toSAX
- write a Transformer
- write a Source (this I hadn't even figured until I read Giacomo's
mail)
I'm really overwhelmed by the spectrum of choices and some guidance
would really be helpful at this time :). What do you developers think?
