As the semantic map editor is moved into knowrob_gui. But the tutorial and document has not been updated. Do anyone know what is the problem with this:

When I compiled the knowrob_gui successfully in groovy on Ubuntu 12.04 and run it

$rosrun knowrob_gui KnowRobGUI

It displays that:

find: ‘/jre/lib/’: No such file or directory Cannot find libjsig ... maybe you need to set JAVA_HOME?

PS: @Moritz would you please update the tutorial if possible?
