Hi, If you have downloaded the vendor-independent package (kosmos-0.2.0RC2.zip), then go to the kosmos-0.2.0RC2/portlet dir and launch that command. If you're using Liferay, plz note that there is dedicated package (kosmos-0.2.0RC2-for-liferay-portal.zip) available! You can download that from the project downloads page, then simply extract it to the /webapps dir of Liferay and voila!
