Cocoon integration
by Marcelo F. Ochoa - Feb 14th 2001 16:12:57
DB Prism plugged into the Apache Cocoon framework is a new way for making
Internet applications with technologies as XML and XSLT. Cocoon is a
presentation framework based on servlet technology, so it can run in any
web server supporting servlet technology. As a presentation framework it
has the responsibility for serving pages requested by the user, applying
first styles as the page needs and transforming static or dynamic XML
content into HTML. Cocoon is also able to perform more sophisticated
formatting, such as XSL:FO rendering on PDF, WML formatting for
WAP-enabled devices, or direct XML serving to XML and XSL aware clients.
The Cocoon project aims to change the way web information is created,
rendered, and served by completely separating document content, style, and
logic.
DB Prism is plugged into the Cocoon framework for the XML creation step.
It then moves the logic to the database, closely allied to the data itself.
The most important characteristic of DB Prism is that unlike in other
technologies, the logic of the application resides in the database as a
stored procedure. The stored procedure could be written in the proprietary
language or in Java. Writing stored procedure in Java with a JDBC or SQLJ
call guarantees portability across different database vendors because there
is a standard defined for this purpose.

Backward compatibilty for Oracle Applications
by Marcelo F. Ochoa - Feb 14th 2001 16:10:18
The main motivation to work like the PLSQL Cartridge of Oracle Web Server
is to allow old technologies to coexist with new ones, helping in the
migration path. Using DB Prism it is possible to run applications made to
work with Oracle Web Server ( OWS ) in the same box or
the latest Oracle Internet Application Server ( IAS ) mod_plsql
without any modifications.
This kind of application includes applications designed with Oracle Designer - Web
Server Generator or Oracle Web DB , and
standalone applications made using the PLSQL HTP toolkit (Html Toolkit
Procedures is group of related procedures or functions written in PLSQL to
make application for the Oracle Web Server architecture). For further
information on how these applications work, refer to the developer's
manuals of these products.
