TopMind Systems has released jLynx 1.2, an open source library for Object / Relational mapping that "lets you persist POJOs and Maps very easily, plus it keeps SQL code and connection configuration in XML. Simple database transactions (i.e. CRUD operations) involving a single POJO require no XML mapping or SQL. jLynx generates JavaBean objects based on your database schema. For example if you have 24 tables and views in your database, jLynx will create 24 objects with properties that map to the field names in each table. The jLynx Generator creates the objects and compiles them. You can also use the generated source instead if you prefer to customize the objects." jLynx is published under a BSD license.
