What's that? "The system property user.dir contains the current user directory." Hmm. I like ${CATALINA_HOME} read only. -------------------- I start tomcat using "${CATALINA_HOME}/bin/catalina.sh start", so adding CATALINA_OPTS='-Duser.dir=/an/appropriate/temp/directory' export CATALINA_OPTS is a workaround. -- nord --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
