I think you're mixing the purpose of appenders and levels.  If everything is
going to the console, and has the same layout, then you only need one
appender.  Then for each package you specify a different level to log at (eg
INFO, DEBUG, ERROR etc). And yes, as Alan said, you can specify a package
name, but it must still be fully qualified.

Example: if the fully qualified package names are 
	com.myorg.webapp.servlets
	com.myorg.webapp.beans
then the following should work:

<appender class="ConsoleAppender" name="CONSOLE">
  ......
</appender>

<logger additivity="false" name="com.myorg.webapp.servlets">
   <level value="DEBUG">
   <appender-ref ref="CONSOLE" />
</logger>

<logger additivity="false" name="com.myorg.webapp.beans">
   <level value="INFO">
   <appender-ref ref="CONSOLE" />
</logger>


This will log DEBUG and above events from the com.myorg.webapp.servlets
package, but only INFO and above from the com.myorg.webapp.beans package.

However, if by CONSOLEVERBOSE you actually wanted more information printed
on each line for a particular package (such as source line or something)
rather than just more "lines" printed, then you will need a seperate
appender as you originally had.  But still make sure you use the fully
qualified class name.

Hope this helps.

Simon
