java - using log4j for clearing a file?

im using log4j to write into a file with the following properties file :

log4j.rootLogger=DEBUG, FA

#File Appender
log4j.appender.FA=org.apache.log4j.FileAppender
log4j.appender.FA.File=temp.ppr
log4j.appender.FA.layout=org.apache.log4j.PatternLayout
log4j.appender.FA.layout.ConversionPattern= %m%n

My problem is , that in each run of my program , i want to clear the file "temp.ppr" , and then write to it efficiently with lo4j? or do you recommend other solutions?

thanks

Have you tried just setting the append property on the FileAppender to false?

log4j.appender.FA.append=false
