Answer 1

I had similar problem. I put the file under src folder and it worked. I did not mention any package name in the log4j2.xml file.

Answer 2

you should put your log4j2.xml into the classpath.

or set "log4j.configurationFile" system property to force to use your log4j2.xml

Please refer to: http://logging.apache.org/log4j/2.x/manual/configuration.html#AutomaticConfiguration

Answer 3

I also faced the same problem.I kept my log4j2.xml file in System environment variable.

Variable name : sys_logroot Variable value : D:\user\gouse

and no logs are created for me.

use the system variable-Dlog4j.configurationFile=path/to/log4j2.xmlSee here

This solve my problem

Answer 4

place log4j2.xml file under src/main/resources. It works

Answer 5

I had the problem, I tried some solutions, but only this worked to me:

Go to web.xml, and add this parameter:

<context-param>
    <param-name>log4jConfiguration</param-name>
    <param-value>log4j2.xml</param-value>
</context-param>

Answer 6

In the documentation of log4j 2: http://logging.apache.org/log4j/2.x/manual/configuration.html#AutomaticConfiguration

"If a JSON file cannot be located the XML ConfigurationFactory will try to locate log4j2.xml on the classpath."

but it is not working with classpath. Instead if we keep it in src folder, then it is working.

<context-param>
    <param-name>log4jConfiguration</param-name>
    <param-value>log4j2.xml</param-value>
</context-param>
