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");

I have an administration console I'm building, and I want to display the

that define where the logs are stored:

<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
