Automate file update

[Nee Kat]

I have a logfile which needs to be rolled over every Thursday.
By this I mean that all the information in the file should be deleted on Thursday and logs written on Friday should start in a new file. I don't know how to do this. I am using BufferedWriter to create the file. Here is the code:

BufferedWriter outFile = new BufferedWriter(new FileWriter("/web/boomerang/dev/log/log.IPSearch",true));

Date currentTime = new java.util.Date() ;
String currentDate = currentTime.toString();
outFile.write(currentDate);
outFile.write(" "+ip_address);
..............................
...............................

Is there a way to this because this code is in a servlet and the logfile is modified when the servlet is invoked.

Thanks in advace.

You can use Log4j for logging.Log4j can be configured outside the code. The conditions you have mentioned is possible using Log4j.
