Answer 1

Debug worked for me. I was using tomcat 8, configured on centos 7. Debug port opened for me after changing 2 settings.

1. Open tomcat/conf/bin/startup.sh and added below lines

export JPDA_ADDRESS=8000
export JPDA_TRANSPORT=dt_socket

2. In the same file startup.sh, added jpda before start command.

exec "$PRGDIR"/"$EXECUTABLE" jpda start "$@"

Restart the tomcat. In eclipse go to Run>Debug configuration>Remote java application>Add host ip and port(8000) where tomcat is running. In my case i required to open 8000 through firewall too.

firewall-cmd --zone=public --permanent --add-port=8000/tcp
firewall-cmd --reload
