The above configuration creates a rolling output file. Once the file reaches 0.5 Mb in size it is renamed by adding an index to its end and a new log file is created. A maximum of 4 log files is kept.
For more information on how to configure log4j please refer to http://logging.apache.org/log4j/docs/.
If you now redeploy your application all the output from your application should be logged in the file you chose.
