Try setting JAVA_HOME.

My settings: echo 'JAVA_HOME=/usr/lib/jvm/default-java export JAVA_HOME PATH=$PATH:$JAVA_HOME/bin export PATH' >> ~/.bashrc

I don't know why. Set JAVA_HOME is part of my own ROS installation process. Maybe someone knows that...

The visualizations for KnowRob are written in Java, and some parts require JAVA_HOME to be set. For me, setting JAVA_HOME to /usr/lib/jvm/java-6-sun works (assuming you have Sun Java 6 installed)
