Avalon is used in lots of places. Projects hosted at apache that use (parts of) avalon include:
Cocoon - See CocoonProjectPages
- James - James
Turbine - TurbineProjectPages
- XML FOP - See FOPProjectPages (work in progress and only slowly)
A non-Apache project that uses Avalon (and Fortress) is Keel, at "http://www.keelframework.org"
Also note http://avalon.apache.org/apps/appselsewhere.html has some more links.
Note: if/when the other Apache projects move to wiki.apache.org we should setup these as InterWiki links.
