Annotion-Based Embedded SQL (JDK 1.5)

I wanna learn how to create and use annotations in JDK 1.5, so I got some idea from voruta.sf.net.
Voruta is an embedded SQL framework using Javadoc's style annotation. Based on the same idea, but mine is more dirty :), I implement data access framework for embedding SQL statement with JDK 1.5 annotation. I call it the SQLWarp. You can download and try it here.
