Cameleon a Framework for developing reliable database applications in a technology independent and predominantly editorial way. User interfaces may be easily exchanged from Swing to HTML and vice versa, and databases may be exchanged in the same manner. The Swing variant framework is established. The HTML user interface is under construction but can be reviewed on the project Webpage ("Test sample application"). Cameleon's target users are programmers who manage midrange data volumes (from thousands to millions of database records) and who prefer simplicity and availability rather than animation. Business features such as security management and parameter administration are supported in the framework. The framework allows web developement without any knowledge of JSP, HTML, Servlets etc. Data input elements (and groups of them) may be used in Java Server Pages.

It uses PHP with MySQL or PostgreSQL as a backend, and is therefore able to manage tons of email accounts independently from your Unix/Linux accounts. Exim for SMTP and Courier for POP/IMAP are fully supported, but postfix, Cyrus, and qmail can be used too.
Wallal is a standalone LDAP-to-Web gateway. It allows you to search, add to, modify, and delete from an LDAP database. It can format entries and validate them upon submission, and the entries displayed are fully configurable. It was designed with a "personal" LDAP server in mind (one that is used primarily as a phonebook). However, it should be reasonably easy to modify it to do more complex operations on a directory.
