Problem in KnowRob

edit

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

please can you explain why this error appears, however I install ros-fuerte-knowrob ?!

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

I do not Know why java at all :(

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)

OK thanka I will try this

sudo add-apt-repository ppa:ferramroberto/java sudo apt-get update sudo apt-get install sun-java6-jre sun-java6-plugin sun-java6-fonts cd /usr/lib/jvm/default-java/jre/lib cd /etc sudo vi bash.bashrc Then I add this and save JAVA_HOME=/usr/lib/jvm/default-java export JAVA_HOME PATH=$PATH:$JAVA_HOM

I do this instructions but when I run mod_vis it does not give an error but stop working at % /opt/ros/fuerte/stacks/knowrob/mod_vis/prolog/init.pl compiled 0.00 sec, 24,464 bytes % /opt/ros/fuerte/stacks/knowrob/mod_vis/prolog/init.pl compiled 0.40 sec, 1,546,852 bytes so what ?!
