[logback-user] How to output all errors to console, and errors+mesgs to logfile?

[Rob]

Hello,

I'm a new user and struggling to achieve the following:
1) All "error" messages must go to stdout and a logfile.
2) Based on com.example.myclass level settings, messages also go to logfile.

My problem is I can't get both requirement 1 and 2 working simultaneously. 
The following results in debug messages going to the console.  Using 
additivity="false" results in errors from com.example.myclass not going to the 
console.

Any suggestion is welcome!

<configuration>
	<appender name="ROLLING" class="ch.qos.logback.core.rolling.RollingFileAppender">
		...
	<appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
		...

	<logger name="com.example.myclass" level="debug">
		<appender-ref ref="ROLLING"/>
	</logger>

	<root level="error">
		<appender-ref ref="CONSOLE"/>
		<appender-ref ref="ROLLING"/>
	</root>
</configuration>

Thanks,
Robert
