Chiya is the fastest (by magnitudes) zero-configuration Java Web Framework based on DI & Adapter pattern and features integrated JDO, AJAX, JQuery plugins, FeedManagement, Webservices and lots on. Idea is to develop application in days, not months.
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
JDO is a Java DeObfuscator that works on class files directly. JDO contains a simple and easy to use GUI that makes automatic deobfuscation of Java projects a one-click operation!
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.
Jpal is yet another persistence layer API for java. It differs from other persistent frameworks (JDO, EJB) because it support full relational object model query (e.g sql join) through natural OO api and allow maximum implementation freedom to implementer
This project is an Eclipse plugin that adds a jdo byte code enhancer nature to your eclipse java build environment. Any jdo byte code enhancer with a command line interface can be utilised.
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.
