Dear all,
I am at a dead end, I hope someone on this mailing list can help me...
I have a web application deployed as an EAR in a JBoss application server,
containing of a .war and many utility jars (managed by gradle)
For various complex reasons, I cannot use "automagic" configuration. Mostly, I
set a few System properties in the code before initialization.
Initialization is done in a servlet which is guaranteed to start first by
WEB-INF/web.xml
Initialization sets system properties then runs
Configurator.initialize(classLoader, new ConfigurationSource(new
FileInputStream(filename)));
or alternatively REconfigure following the FAQ at
https://logging.apache.org/log4j/log4j-2.4/faq.html
However, no matter what I do, I end up with TWO LoggerContext instances
(I see that during initialization trace and later in
log4jContextFactory.getSelector().getLoggerContexts())
and the "wrong" LoggerContext has a RootLogger with level ERROR and NO
appenders and all of the loggers that are actually used and touched in the
application are under the "wrong" LoggerContext and have log level ERROR and do
not log. Only some loggers which are directly used in the web application .war
are configured correctly.
for all the "wrong" loggers I get a message like
loggerContext name=24421690 - logger name=org.apache.velocity.loader.webapp
level=ERROR appenders=
WARN StatusLogger The Logger was created with the message factory
org.apache.logging.log4j.message.ParameterizedMessageFactory@63e37b6c and is
now requested with the message factory
org.apache.logging.log4j.message.ParameterizedMessageFactory@19334714, which
may create log events with unexpected formatting.
I did not ask for a second LoggerContext and I do not understand why it is
created.
In fact is is created inside the loggerContext.setConfigLocation(file.toURI())
of the "only" LoggerContext I know
Please help me initialize my log4j properly from a ConfigurationSource
Here is some trace log, where the "wrong" LoggerContext is created without a
configuration - and all subsequent loggers are put under THAT loggerContext
