SQL2JAVA is a free, open source object-relational mapping tool.

It enables Java developers to quickly map a relational database schema to a set of classes.

The generated source code uses standard JDBC methods for persistence, and there is no runtime library required.

SQL2JAVA is simple

SQL2JAVA source code is simple, its design is simple, so it is easily modifiable and extendable to fit your needs.

The generated code is simple and documented, so it is easily readable.

SQL2JAVA generates code

Is that supposed to be a key feature ?

Isn't hibernate and consors generating on-the-fly code using dynamic proxies that are driven by XML configuration files whom are themselves generated via embeded xdoclet javadoc tags ?

The point is that this kind of software is great, often technologically speaking they are damn great, but their learning curve are damn steep, and when an exception arise, you are damn lost ...

With SQL2JAVA if you have an exception, you have the filename and its line number, so you just read the line and you know EXACTLY what is the exception about !
