Hi,
I am using tomcat to run jsp file,
my question is how can force my server to create log file ?

I'm new into tomcat, so please be gentle.

Thanks

You can use the JAVA_OPTS environment variable.
It is similar to enabling gc logging for a normal JVM just pass the same options in JAVA_OPTS and restart tomcat.

example on Linux:-

export JAVA_OPTS=-verbose:gc -Xloggc:logfile

the above should work, but remember the 'logfile' will be cleared at every JVM restart.
