Oxygen-heads: I have a log4j.properties file for testing a plugin that integrates Oxygen and RSuite. I am currently using Mac OS X. log4j.appender.R.File=oxygen-rsuite-plugin.log If I use oxygenMac.sh from the command-line, the oxygen-rsuite-plugin.log file shows up in the current directory where I run the command. If I launch Oxygen from the "open" command on Mac OS X (from an applet in FireFox), then the current working directory is in some random place (that I cannot find). Log4j permits variable substitution in the log4j.properties, from system properties. Are there sysem properties set by Oxygen for the installation directory or some other place where I can locate the log file so it will be in a consistent place? I would like to be able to specify something like this in the log4j.properties file: log4j.appender.R.File=${oxygen.home}/oxygen-rsuite-plugin.log Thanks, Michael Roberts
