What you need is to set package logger access at Category or Logger level, to achive this try following :

# make default and debugLogFile both as root category
log4j.rootCategory=, debugLogFile

# set package wide logger Level (via Category, older way)
log4j.category.mypack=INFO

# OR set package wide logger Level (via Logger, newer way)
log4j.logger.mypack=INFO

# an example of turning all apache package logs to WARN
log4j.category.org.apache=WARN
