Groupware

Looking in :
http://sourceforge.net/search/?type_of_search=soft&exact=1&forum_id=0&group_id=0&atid=0&words=groupware+java&Search=Search , I allready identified :

• http://sourceforge.net/projects/centraview : a commercial application recently gone opensource, focuses on Business Management and CRM
• http://groupware.ivata.org/    : got an acceptable web demo; poorly internationalized: refuses accents in new notes
• JiCal is original : it scans directories for *.ics files (evolution or korganizer) and converts them to RFC2445 format to be published on a web server; then they can be used as free busy files by evolution (or outlook)
• http://lucane.org/ : mainly non-web, with a special client
• http://jeteam.sourceforge.net/ : oriented towards software development tasks ; the demo site is dead; seems to be using EJB 2 :-(
•  Become efficient with Coefficient : I like the motto ! seems to work with or without EBJ (?) ; the demo site is dead (2 times)
•  DataShare : used to simultaneously collaborate using chat, paint, desktop sharing, and audio-video conferencing; it's not a Web app.
• open-xchange.org : can be accessed via any modern web browser and multiple fat clients like KDE Kontact, Apples iCAL, Konqueror, Mozilla Calendar, and many more, based on open standards and interfaces. Has both a commercial and open-source version; developped in Java AND Perl :-( .
