A few months ago my friend Andrea published a screencast titled "Run jAPS in 10 minutes" which shows how to run jAPS 2.0 version 2.0.6.
So now that video is old :) It's old but still valid!
You can still follow the entire video and just remember that you HAVE TO configure /META-INF/context.xml instead of /WEB-INF/conf/systemParams.properties!!
There was many changes between 2.0.6 and 2.0.8 but in order to run jAPS 2.0 (2.0.8) in 10 minutes follow the old video guide and just editcontext.xml instead of systemParams.properties.
...So I suppose Andrea will make a new video ASAP :) maybe with jAPS 2.0.10 :D
