I’ve begun off-hours work on an experimental project to persist ROME beans into a back-end database. I started with straight JDBC connections and my own xml mapping structure, but Robert Cooper of FeedPod fame turned me onto Castor. After getting over my initial misgivings, I quickly warmed to the suggestion.

Myth: Castor is dead. Fact: A review of the Castor website shows a lot of activity and new releases in 2004.

There are various resources out there on getting up to speed with Castor… some better than others. Here is my suggested reading list for anyone investigating Castor JDO on their own:

1. Using Castor JDO
2. Mapping Castor Objects to a Database with Castor JDO
3. Cultivating your relationship with Castor JDO
4. Data Access Object (DAO) Design Pattern

This last link is helpful to understand some of the more elegant ways to handle persisting/retrieving objects through any mechanism, Castor included.

I made a quick “Powered By ROME” badge. (It’ll serve as a placeholder until somebody comes up with something better… which shouldn’t take long.)

I did the happy dance today when I discovered another business use for RSS that has already been deployed in the wild. A recent version of Jira (think Bugzilla, but cooler and only free for open source projects) provides RSS feeds for any issue in the system.

For example, here’s a Jira issue opened in the Jetspeed 2 project where they have decided to use the Rome framework for RSS:

http://issues.apache.org/jira/browse/JS2-191?page=history

The little [xml] link at the top of the left sidebar gives the RSS feed for that issue so that you can be notified when the issue is updated. Very nice.

I use Jira at work, so I’m pretty jazzed to have it already available.

If you’re a java developer, you should check out ROME, a Java library designed to make consuming RSS/Atom feeds, well, silly-simple. The goal of ROME is to pull in ANY syndication feed type (RSS .90, .91, .92, Atom .3, etc.) and populate canonical java beans. From what I’ve seen, it is all kinds of nifty, even though the current release is only 0.5.

Furthermore, it proved completely trivial to run a test class (using the ROME Fetcher subproject) and grab the /. feed, my own feed, and a bevy of others.

The guys working on the ROME project have been pretty responsive to the user mailing lists, so I’m getting good vibes about the whole deal. (Or dealio, as a certain nifty monkey might say.) I’m currently cooking up a personal project using Rome/Fetcher so I can dig further. More on that in another post.
