recompiling, repackagin and redeploying I get this error after trying to
estimate a preference:

Nevertheless, the recommender builds the diffs successfully. I also
tried to pruge the tomcat server and install it again but that doesn't
help neither.
Another information: I got the error with the disabled attachment
support with the old version too and it worked perfectly!

Oops that's a small bug. It was not clearing the estimate for an item that
is already known to a user in this case. Try the change I just committed to
SVN.

Ok if it should be so, why doesn't it work?
I made the following:
* estimatePreference userID=1 itemID=1 -> 6....
* setPreference userID=1 itemID=1 value=4.0
* estimatePreference userID=1 itemID=1 -> 6.... and not 4.0
So, how can I change that behaviour?
