Disable logging on mockservice war deployment

Hi.

Is there a way to disable logging on .war deployments of SoapUI mockservices?

Im getting following errors and would rather not spend time trying to configure log4j.

log4j:ERROR setFile(null,true) call failed.
java.io.FileNotFoundException: soapui-errors.log (Access is denied)
