Define loggers and appenders for each war! Then if you see that messages get logged twice find who is logging it. Then set the additivity for that logger to false, and that's prevents that logrecords from this identified logger are propagated upward in the logger hierarchy to the next more common logger. Look to loggers as a tree where only the loggeers at the leafe positioon shall log and by using additivity=false for that logger the leave logger will not propagate the message to the trees and more toward the root logger.

But, because of they run in the same jvm, i am not sure whether it is possible or not. how can i handle this issue? By the way, the war applications are spring projects. i created two log4j config files (log4j_app1.xml and log4j_app2.xml) and instantiated them in the applicationcontexts but it did not solve the problem.
