Marcelo took this project over and changed its name (partially in response to a suggestion from Steve Muench of Oracle Corporation). The application has since gone from strength to strength, riding on the Apache JServ web server system (before iAS itself got there).

DB Prism is an open source framework designed to generate dynamic XML from an Oracle database (other databases are expected to be supported in the future). The DB Prism servlet engine works in two different modes: it can be run as a standalone servlet, or it can be plugged into the Cocoon publishing framework. When used with Cocoon, DB Prism provides a new way to make Internet applications work with technologies like XML and XSLT.

DB Prism can also be used both to emulate the old Oracle Web Application Server PL/SQL cartridge, and to work with the latest Oracle iAS products, in conjunction with the mod_plsql Apache module (which extends Apache to handle PL/SQL web content).
