In order to turn on DEBUG, you must edit the log4j.properties file and then restart the NexENUM application.
Edit log4j.properties
$ cd $NexENUM_HOME/WebServer/webapps/enum/WEB-INF/classes
$ vi log4j.properties
Change this:
log4j.rootLogger=INFO, ROLLING_LOG_FILE_BY_DAY
to this:
#log4j.rootLogger=INFO, ROLLING_LOG_FILE_BY_DAY
log4j.rootLogger=DEBUG, ROLLING_LOG_FILE_BY_DAY
Restart NexENUM
$ cd $NexENUM_HOME
$ ./stop_ENUM.sh
$ ./run_ENUM.sh
Note:
ENUM log file = $NexENUM_HOME/WebServer/webapps/enum/logs/rolling-by-daily.log
