Re: [JBoss-user] JMX and ear-scope (too much "protection"?)

[Michael B. <mic...@li...>]

Hi Adrian,

Meanwhile I've considered to lookup the MBeanRegistry via the MBeanServer
and registering through its service, where I can specify the Map. (I've not
programmed this yet, we have a "going live" today in Hamburg which I support
remotely.)

Do you think this could work?

(N.B.: I think your solution is preferable, unless - of course - it 
breaks other things.
And Scott Stark want's to get out the 3.2 beta this weekend...)

Regards,
Michael Bartmann
