...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
JAXBBuilder is an eclipse plugin for generating Java classes directly from XML schema, XML or JSON files. The plugin detects document changes and re-generates Java code via Castor or XJC. It includes a JAXB project wizard, and configuration pages
Integrates Castor support into Eclipse. Provides incremental generation of Java code to support Castor XML marshalling based on XML Schema files, as well as a visual Castor XML Binding editor.
Pluggable "Unit of Work" framework [based on EAP by Martin Fowler] for use with most popular open source and professional OR/M tools, such as: Hibernate, KodoJDO, Castor JDO, and iBATIS.

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.
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
JBuilder Wizard OpenTool which offers one facilitated way to generate java source code through O/R mapping, such as Exolab's Castor JDO, DAO etc. It may also generate other adjunction files according to your needs, such as Castor JDO mapping file.
JOrganizer is a webbased PIM (Personal Information Manager), written in Java. With it, you can manage your contacts, emails, time and more. It is based on JSP, Servlets, Struts, Castor, the xml.apache.org API's and other Open Source projects.
TogMap is a module for the CASE Tool Together which generates
XML-mapping-files for OR-Mappers. It takes an existing
object model, which you can augment by OR-specific markers, and produces an XML-mapping file. Currently only for Castor-JDO.
