I have an administration console I'm building, and I want to display the logs created in Logback for my application. However, where those logs are stored is different per environment. I have several property files that define where the logs are stored: <configuration> <property resource='log.properties'/> <property resource='log.${ENV:-prod}.properties'/> <appender name="FILE" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>${log.dir}/sync.log</file> ...</configuration> I'd like to find the value of ${log.dir} from Logback's Java API. I'd tried the following, but it doesn't have any of the properties defined in the resources. For example: LoggerContext loggerContext = (LoggerContext) LoggerFactory.getILoggerFactory(); String logDir = loggerContext.getProperty("log.dir"); // this always returns null So my question is what API calls should I be using? Thanks Charlie If you'd rather have the stackoverflow karma I originally posted this there: http://stackoverflow.com/questions/14271253/access-properties-defined-in-log...
