Would you guys happen to know how I can configure log4J to write to different log files which will contain a unique identifier(not a date) that is present within the code block during the time of writing?
You can write log files in what ever manner you want. You can append unique identifier also in log file name. What you need to do is to write custom file appender. You need to define that custom file appender class name in the log4j.xml file. In this way you can get whatever you want.
Search on google, you will get samples how to write custom file appender for log4j.
