The application is a very simple maven application, I put the log4j.properties in resources folder, then I run mvn clean package, then in ecllipse, I right click the project and choose run as java application, but error

No appenders could be found for logger (x.y.TestLog4j)
Please initialize the log4j system properly.


I think the application cannot load the log4j.properties, but how to let the application find the log4.properties?
I check api and there is some
PropertyConfigurator.configure(URL);
but I do not know how to create the URL. any help is appreciated.

the log4j.properties is as follow:

x=ERROR, A1, A2
log4j.appender.A1=org.apache.log4j.ConsoleAppender


log4j.appender.A1.layout=org.apache.log4j.PatternLayout


log4j.appender.A1.layout.ConversionPattern=%d %-5p (%13F:%L) %3x - %m%n

# Appender A2 writes to the file "test".
log4j.appender.A2=org.apache.log4j.DailyRollingFileAppender
log4j.appender.A2.DatePattern='.'yyyy-MM-dd
log4j.appender.A2.File=./debugleveldemo_logs/debugleveldemo.log


# Appender A2 uses the PatternLayout.
log4j.appender.A2.layout=org.apache.log4j.PatternLayout
log4j.appender.A2.layout.ConversionPattern=%d %-5p [%t] %-17c{2} (%13F:%L) %3x - %m%n

When maven builds the project and you run the target app, the log4j properties file must be in the runtime CLASSPATH at its root. For webapps, that mean in the WEB-INF/classes directory.
