Not really, because you have to lookup the Eros Service in order to
have the Logging handler supplied to you, hence you can't (or at least
I don't think you can) put it in the logging.properties file. Although
I could have a look at it a bit deeper and try and think of some work
around

Again this is because this logging handler is downloaded remotely,
after the JVM has been started and probably after loggin.properties
file has been parsed and initialised

I am trying this now but I don't think my Rio

I'll look into it.

No, all you really need is 1 eros instance, but you have to do a
service lookup for each service/client you want to use Eros logging
in.

Okay the source refres to some form of Prxy perparer done by your
service (part of Jini's security framework) - you don't actually need
this. you would just change this line

             eros = (ErosService) preparer.prepareProxy(svc.service);
to
             eros = (ErosService) svc.service;

I am working on allowing you to have differnet application labels
logged on a single logger depending on which logger (package name)
you're using, which helps for things like containers, etc. To be
honest I'll probably put a lot of that boilerplate code into some form
of Utility class once I get 5 spare mins.

Hope this helps
