NVDCMS is an advanced opensource (BSD License) Java/EJB-CMP-2.0/XML/XSLT Content Management System that can use any SQL database for content persistence. NVDCMS supports Virtual Hosting, SOAP/WebServices, custom XML transactionnal business process language and much more ;)

Why should I use NVDCMS?

NVDCMS has been inspired by the Apache Cocoon engine, but, it's now way ahead of Cocoon as it includes full dataflow processing structure/language. From the end user view point, NVDCMS abstracts all relationnal database concerns, using XML object mapping and simple command language.

 NVDCMS is free and OpenSourced (BSD License): can easily be extended by anyone having a little Java knowledge.
NVDCMS is robust: many plateforms using NVDCMS are in production stage since more than one year.
 NVDCMS is 100% XML oriented: it processes the XML document using a simple command language and XML object data structures. Actually, you will probably have a harder time designing your XSL stylesheets than your NVDCMS compatible XML documents.
 NVDCMS is fast (even as fast as static HTML page web server): using advanced hierachical caching structure at each stage of processing. In fact, we have been able to saturate our 100Mbit ethernet LAN during our stress test on "after-processing cached XML document".
NVDCMS is scalable: with its 3 tiers architecture, NVDCMS can sustain heavy load on dynamic pages, distributing each piece in server cluster. In fact, all frontals use a distributed cache (based on JavaGroups) allowing classical weight-round-robin HTTP load balancing.
 NVDCMS includes an internal search engine: all data stored is indexed on the fly inside the internal search engine.

Why shouldn't I use NVDCMS?

You should :). The single drawback of using a 3 tiers Java based architecture (database, EJB server, HTTP frondend) on a single machine is actually memory. Anyway, you should be able to run all 3 components with one JVM instance but expect some pretty heavy memory usage.

Also NVDCMS does not comes with a point and click IDE, allowing WYSIWYG web conception. We believe that it should not be a good reason to avoid NVDCMS (a decent XML/XSLT IDE is yet to be seen, if ever).

Can I download a ready to go binary package?

Not yet. We're currently working on a simple "all in one" distribution, but you can still get the source in CVS repository though.


You can download features tech sheet. Here is a short key features list:
