DataNucleus provides Java data persistence to a range of datastores using JDO/JPA/REST APIs. *** Note that code development is no longer on SourceForge (code on SourceForge is for versions up to 3.3.5 only) ***
WhiteBear is a set of foundation classes for database engines written in Java. It supports object and relational database, is highly portable and may be used in embedded or server environment. Project has been created from scratch and plan to includes storage engine, server, SQL interpreter, ODBC, JDBC and JDO interface
Druid is a GUI tool for database build and management. Users can add/change/delete DB objects (tables, fields, etc). Druid generates for you: SQL scripts, docs in XHTML, PDF, DocBook, etc; code in C, C++ & Java Beans even for JDO and support Castor & OJB
PriDE is a thin and high-performance Java O/R mapper for relational databases. It does not follow any persistence management standards like JDO or EJB-CMP but relies on common design patterns and is production-proved in both J2SE and J2EE environments.
Open Source Reporting & Data Visualization Platform
BIRT is an open source technology platform used to create data visualizations and reports that can be embedded into rich client and web applications. Developers who use BIRT Designer are able to access information from multiple data sources easily and quickly in order to create reports and applications with stunning data visualizations.
Actuate now provides a free report server, BIRT iHub F-Type, to deploy BIRT content so developers don't have to build their own infrastructure. With a...
Cumulus4j is an encryption plug-in for DataNucleus. Applications can thus use JDO or JPA to persist their data into every common database. Using the Bouncy Castle cryptography libs, it provides strong encryption via AES, TwoFish or other algorithms.
A trading platform including ERP, CRM, and accounting
JFire is a trading platform including ERP, CRM, accounting (full double-entry) and cross-organisation-trading written in Java based on J2EE, JDO and the Eclipse RCP. See http://www.jfire.net for more information.
TriActive JDO (TJDO) is an open source implementation of Sun's Java Data Objects (JDO) specification, designed to support transparent persistence using any JDBC-compliant database. It auto-generates DDL and auto-validates DB structure at runtime.
Gaea allows you to view/modify Object Databases with JDO standard. Operations on instances and class structures on the fly. A nigh-complete OQL library is embedded in the project and can easily be used by third-party software to attain OQL compatibility
Real-time error alerts, performance insights, and anomaly detection across your full stack. Free 30-day trial.

Instant notifications on deployments, anomaly triggers for memory spikes or error surges, and seamless log management. Works out of the box with Rails, Django, Express, Phoenix, Next.js, and dozens more. Starts at $23/month with no hidden fees.
A simple SQL Query -> Java Object mapping layer. Simpler than Hibernate or JDO, and much lighter weight. Compatible with the JDBC 4, EoD API from Java 6 beta.
A complete, fast, previously commercial, JDO 1.0.1 implementation for databases, opened by Versant in 2005 and then abandoned in early 2006. The design-time code is already in Eclipse Dali. This project is the original source drop, including the runtime.
Middlegen is a free general-purpose database-driven code generation engine based on JDBC, Velocity, Ant and XDoclet. If you already have a database, you can use Middlegen to generate EJB (CMP 2.0), Hibernate, JDO and JSP/Struts source code.
Orient is 100% Pure ODBMS. It works with classes and objects instead of tables and records. Orient supports C++ language using ODMG 3.0 interface and Java using JDO 1.0.
It's available as Just Edition, a small library, or as Enterprise Edition with dis
If your project demands you to persist java objects in any environment (J2EE etc), use standards but switch to any standards such as JDO, EJB, Hibernate anytime,
use default mapping for build from the scratch apps "EasyPersistence" is your solution
Object Relational Persistence and Object-Based SQL Query API. Similar to that of Hibernate or JDO but much better structured design. This API has several layers of abstraction to be useful for nearly any situation.
This project is a feature-preview tool for JDO with JDK5's annotation usage.
It removes away the step of writing metadata files or modifying them when the model classes are greatly changed. An Ant task is provided to automatically do this step for you.
This Eclipse plugin makes easy and fast to develop transaction applications in Java using JDO drivers. This tool integrates the JDO enhance command in JDT building process.
XORM is an extensible object-relational mapping layer for Java
applications. It provides interface-based persistence to RDBMSs using the Java Data Objects (JDO) API while allowing developers to focus on the object model, not the physical layer.
Java disk/CD/DVD/HD/whatever cataloguer designed to allow the storage and search of different types of data. Hibernate or JDO will be used for catalog storage and maybe some native functions for volume data retrieval (serial and label).
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.
AutoSQL provides a simple and easy to use framework meant to be a substitute for J2EE Entity beans and JDO. AutoSQL data objects give just the right abstraction from a writing SQL without being too far removed from the power of SQL.
The Castor Taglib allows you to execute OQL queries in your JSP page
(using Castor JD0). It also helps you to integrate Castor JDO with Java application servers like Tomcat, making use of JNDI and Tyrex for managed transactions. In future releases other
This project contains an component to building JDO applications with Castor (http://castor.exolab.org/). It's allow easy using of mappings with building OQL queries.
