configuring individually loggingf for every war application in an ear project
My ear project consists of two war applications. i want to create logs
individually for every war. i mean every war projects must create its own
logs. 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.
WAR_APP1 applcaitoncontext.xml :

AW: configuring individually loggingf for every war application in an ear project
Posted by Stadelmann Josef <jo...@axa-winterthur.ch>.
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.
My apps has many loggers .....

Re: configuring individually loggingf for every war application in an ear project
Posted by Jacob Kjome <ho...@visi.com>.
If the webapps are configured to use child-first, or parent-last, classloading
and log4j.jar is in WEB-INF/lib and log4j.xml is in WEB-INF/classes (or you
specify the config path yourself using the Spring configuration utility), then
logging should be separated.
Shared libraries located outside of WEB-INF/lib (such as in APP-INF/lib under
Weblogic) can be problematic since they'll have dependency on Log4j and won't
be able to reference it under each webapp's WEB-INF/lib.
The other option is a repository selector, but that entails some more
complication. There's documentation for it in the logging-log4j wiki [1].
You may still end up with problems when shared libraries log using static
loggers, though, since they will be tied to the configuration of the first app
that accesses them.
