I tried the usual:
- CRX from Day.com: not (yet) stable
- KnowledgeTree Community: couldn't get it to work (unless perhaps you buy the commercial version?)
- Nuxeo: very, very expensive, but looks good (is there a community version available?)
- yet a few more
I also installed Alfresco, which seems to be the best out there in terms of functions it offers; I'm quite impressed by it, to be honest. However, it's very slow, sometimes taking a few minutes to check-in a document. It also takes quite a lot of memory (maybe due to Java?). It also has some issues dealing with Illustrator documents.
Is there a CMIS server available that can connect to Adobe Drive (CMIS) and not running on Java?
I just need the Check-in/out functions through Adobe Drive 2.1 or 3.0 CMIS.
UPDATE [20/02/2012]
After playing with the above-mentioned software for a while, I can (personally) affirm that Alfresco is the best among all (free) available software. I'm running the community version 4.0.d. It seems pretty stable and the installation + connexion to Adobe Drive 3.0.1 via the CMIS connector is seamless; (FYI in Drive: cmis://127.0.0.1:8080/alfresco/service/cmis).

@NicolasRaoul is right. CMIS not running on Java, as specified in the title => Nuxeo. Hence @JulienCarsique's answer accepted/upvoted.
About Nuxeo, it is free for use. There's no "community" or "enterprise" versions but a unique Open-Source, free and enterprise-ready version.
