Hi again guys, I was trying to do this patch on an Xubuntu 11.10 of one of my group members and after I do the ant jar command it says that cannot find the Listen class and so on for the other java programs.
I think is a nesC problem, but i can't find what. The output of the ant jar command is in this file http://db.tt/BAKvtmgE. Thanks for your help.
