JOR is a Java Object Relation mapping tool that is very simple to use. It works with all mayor databases and requires only minimal coding effort. JOR strictly follows the POJO / POJI (Plain Old Java Objects / Plain Old Java Interfaces) model.
Jaxor provides a java code generation engine for creating an object to relationalmapping layer based upon XML metadata. SQL is generated as well as an extensible mapping layer.
RDBS2J is a GUI based mapping tool from relational database schema to persistent java classes which use JDO as persistence mechanism. The mapping can be modified by the GUI. The current version is designed to create code for Apache-OJB.
JDBC-based API to build always valid SQL statements. Other enhancements are: automatic table name and columns completions inside Java code, alias support, prepared statement parameter (?) management, SQL functions...
rdb2oo is a project to create source code for classes which correspond to tables in a relational database.
rdb2oo is also about creating an object oriented abstraction layer for simple database access.
Cartographer is a simple,efficient objectrelational mapper engine. It provides rapid access to relational data using lightweight data and factory java objects.
Based on a subproject, called Gerbo, it does the objectmapping of a Relational Database. It is like torque and object bridge, but simplier.
The full project will have a GUI to make instrospection in a already created database and create the OR. Java.
Sick of ObjectRelationalmapping systems that require a ton of configuration (xml or otherwise)? SimpleJDE aims to provide a simple clean mechanism for relational-object interchange with (near) pure java semantics.

Java Object to Relational (O/R) mapping system that works with any J2EE compliant application server. Draw your class/ER diagram in Rational Rose and let JOB generate the database and Java code from your Ant build script.
OpenORM is an OpenSource ObjectRelationalmapping broker based on Scott Ambler whitepapers.
It's developed on C++ and the objects that it persist are CORBA objects.
We are currently using omniORB2 as our ORB and PostgreSQL as our database server.
A lightweight ORM and SQL schema generator meant as a simpler alternative to Hibernate, etc. with the goal of bringing Rails-like functionality and rapid development to Java. Operates on plain Java classes.
Eclipse GMF/EMF based graphical editor for creating ORM diagrams (object-relationalMapping) and code generator. Three cartridges (based on openArchitectureWare) are provided currently: Java Persistence API (JPA), Grails ORM (GORM) and Django Models.
The BizMDA platform will be the next-level development platform for developing large-scale enterprise SOA software solutions using MDA technology, jBPM, JBossRules and Wicket.
drawcode é um plugin do eclipse para edição de diagramas de classe e NS(Nassi & Shneiderman), com a possibilidade de gerar código a partir da associação destes 2 tipos de diagramas.
spag4j is a code generator written in Java to produce Java code for accessing a stored procedure layer from a database. Currently it supports stored procedures written in an Oracle. It produces either an EJB3 Java layer or simple static access methods.
