This sort of confusion is almost always caused by some other configuration
file being loaded rather than the one you expect. I suggest setting
-Dlog4j.debug=true on the command line (in this case, the command line
starting the appserver), which will cause Log4j to provide information on how
it is configuring the application.
Note that it's also possible the the correct config file is being loaded, but
then some application code is dynamically reconfiguring without you realizing
it. Ensure that no code is manually configuration Log4j after initialization.

log4j.appender.A1.layout.ConversionPattern=%d %-5p (%13F:%L) %3x -%m%n
then in my web application I wrote
private static Logger logger = Logger.getLogger(MyWebApp.class);
logger.debug("debug");
logger.warn("warn");
the output is as expected, only "warn" will be shown.
but in my jar application, I wrote
private static Logger logger = Logger.getLogger(JarApp.class);
logger.warn("warn in jar");
there is no output in console!!!
and if I change the log4j.properties log level to DEBUG
log4j.rootLogger=, A1
then the "warn in jar" will be shown in console, but with %-5p shown as
DEBUG.
That is, even in my jar application, I wrote
logger.warn("warn in jar");
log4j still treat it as DEBUG level, why will this happen?
I am using log4j-1.2.16.jar
