Hi,

I am getting the following error
"log4j:ERROR setFile(null,true) call failed." When i try to run the application.

The below code is the sample class file which is used for put properties into the the Properties file.



In the action class, I am calling the above class to write the logger


When I try to run the application, it is giving me the following error when trying to write it to the log file

log4j:ERROR setFile(null,true) call failed.
