I executed the author instance on my tomcat server and when i try to access it via "<ip address>:4502" it could not connect.
executed netstat, showed that
tcp6 0 0 :::4502 :::* LISTEN
did i start the instance wrongly ? how can i change it to run on tcp instead ?
Tomcat seems to be listening on only the IPv6. At $JAVA_OPTS in /etc/profile aet the value of -Djava.net.preferIPv4Stack=true and verify.
