log4j.properties

Sample log4j property file, logging only to file, if you want console add 'stdout' in the rootlogger and remove the comments in the section below.
I included hibernate and spring logging relevant

logback asyncappender

Since 1.0.4 logback has the famous async appender we all waited for at least me.
It's great news, not to use any custom appenders or custom async appender but their in house.

Just to inform you.
