There's no 'activemq-data' or 'activemq-data/localhost' or 'activemq-data/localhost/KahaDB', so create it:
# mkdir -p /usr/share/activemq/activemq-data/localhost/
# chown -R activemq:activemq /usr/share/activemq/activemq-data/localhost/
# service activemq restart
Look at the logs again, use lsof on the port:
# tail /var/log/activemq/activemq.log
