Hi Charlie, By default, properties are defined in "local" scope [1]. However, you can force a property to have context scope, in which case it's pretty easy to get the value of the property: LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory(); String val = lc.getProperty(aString); Defining properties in "context" scope is considered a little heavy handed. Instead of defining all/many properties in context scope, you could define only a single property in context scope. Here is an example: <configuration> <!-- get many props from a file --> <property resource='log.properties'/> <-- set only one to be in context scope --> <property scope="context" name="log.dir.ctx" value="${log.dir}" /> ... </configuration> You could then obtain the value you are looking for with: LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory(); String val = lc.getProperty("log.dir.ctx"); HTH, [1] http://logback.qos.ch/manual/configuration.html#scopes On 11.01.2013 22:43, Charlie Hubbard wrote:

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
