Thank you for your reply. I have tried to place the log4j.jar in the share
library of the oc4j instance, and then import this during application
deployment. This would result the behavior i have mentioned at the my first
post message.
I don't know anything about OC4J, but if it allows for child-first (also
called parent-last) classloading per application, then you can add log4j.jar
to WEB-INF/lib and log4j.properties (or log4j.xml) to WEB-INF/classes. This
will result in each application having its own instance of Log4j and,
therefore, enable both to auto-configure themselves with no clashes between
applications.

Whether the behavior is "strange" or not depends on how you are
configuring
Log4j and how the classloader hierarchy is set up under OC4J... as well as
where Log4j.jar exists in the classloader hierarchy.
I'm guessing you are letting Log4j auto-configure itself by finding your
log4j.properties in the classpath. If Log4j is in the OC4J classpath, I
would
only expect this to happen once, which would set up a single logger
repository
(the default one) which all applications would use.
Rather than speculate anymore about what could possibly be happening, I'll
let
you describe you setup in greater detail. We'll be able to draw more
precise
conclusions from that.

Hi,
I have deployed two applications into same OC4J instance, the version of
OC4J is 10.1.3.1.
The strange thing is the second applications will ignore it's oc4j
properties, and use the first applications log4j.propeties, here is the
log4j.properties in this two application:
