The jBATIS persistence framework will help you to significantly reduce the amount of Java code that you normally need to access a relational database. iBATIS simply maps JavaBeans to SQL statements using a very simple XML descriptor.

The newest version!

/**
 * The CommonAbstractCriteria interface defines functionality 
 * that is common to both top-level criteria queries and subqueries as 
 * well as to update and delete criteria operations.
 * It is not intended to be used directly in query construction.
 *
 *  Note that criteria queries and criteria update and delete operations
 * are typed differently.
 * Criteria queries are typed according to the query result type.
 * Update and delete operations are typed according to the target of the
 * update or delete.
