BEFORE YOU POST, search the faq at <http://java.apache.org/faq/>
WHEN YOU POST, include all relevant version numbers, log files,
and configuration files. Don't make us guess your problem!!!
----------------------------------------------------------------
Script Process:
1. cp file to new archive file
2. cat /dev/null > file - clears the file.
No need to restart server - no fuss.
Never done it myself...but 'ave a go mate.
PS: maybe unix only soln.
