Roller persistence
I'm playing with Roller 5RC and was trying to add a few tables and
pojos for kicks. Is there any docs on the design? I see the
persistence manager stuff under planet-business. Being new to roller,
the design isn't obvious to me after spending several hours studying
it.
any help is greatly appreciated.

Interesting.
One thing is for sure: I don't have an appetite for converting the
existing XML over to annotations ;-)

Having used a variety of ORM over the years, I prefer the XML myself.
On most of the projects I've worked on, using XML allowed us to map 1
table to multiple objects and the reverse. Sometimes it's useful to
map 1 object to one or more views for convenience. Using annotations
limits you to 1-to-1 mapping. In the case of roller, the model isn't
that complicated, so it might not be an issue.

Yes. The JPA mappings are there and moving forward, I'd like to see us
switch over to using annotations rather than the separate XML files.
It is possible to mix them in one app and, I believe, we are already
doing so.

Thanks for the response.
I was able to muddle through and figured out the POJO directory on
tuesday. I also managed to figure out the db script creation process.
Looking at the source, it appears the jpa mappings are in
"weblogger-business\src\main\resources\org\apache\roller\weblogger\pojos"
is that the correct?
thanks

Re: Roller persistence

Hi Peter,
There are some developer resources here on the wiki:
https://cwiki.apache.org/confluence/x/D84
There is a data model diagram for Roller 4 here:
http://rollerweblogger.org/roller/resource/datamodel40.png
In Roller 5, look at the weblogger-business module. It has the Manager
interfaces that handle persistence and backend "business" logic. To
add a new POJO you need to add a new Java class (see
org.apache.roller.weblogger.pojos) and add new methods to a Manager
interface, or possibly add an entirely new Manager for a set of
related new POJOs.
I'd be happy to answer specific questions or chat via phone to help
you get started.
Thanks,
Dave
