I am using slf4j 1.7.5,logback 1.0.3.

In my app i am using application context to set app name as per given example.

Is it possible for multiple JEE applications to share the same configuration file but without stepping on each other's toes?

Every thing is fine intially and one common xml file is writing in different log files but when i am changing log level its not reading applicationName and start writing in "application-name_IS_UNDEFINED1.log" File.

Why this behaviour?
