Aaron,

I'm a little confused now. When you used -DDEBUG_VERBOSE on the runline
did that change the amount of information that was logged or not?

If it *did* suppress a lot of INFO messages, then that indicates that
jetty is running with it's own logging mechanism enabled. If it *didn't*,
then that indicates that it is running using commons logging and the usual
commons logging discovery mechanism.

In any case, the easiest thing to do would be for us to give you 
a new Jetty with the JSR154 servlet log message sent to a different
logger (your point #2).

Also, your suggestion to prefix the ServletContext log messages with
a standard prefix so it can be easily configured in, for eg, log4j is
a good one. We will also implement that. The prefix will most likely
be "org.mortbay.context".

We'll get the release done ASAP, but it would be helpful to know what 
is the timing for a geronimo 1.0 release?

cheers
Jan
