Subject Re: Can GBean get its configuration ClassLoader?
Date Thu, 18 Nov 2004 18:54:28 GMT

Thanks.  BTW, as a note for anyone else who's interested, GBeanMBean has a 
section at the bottom defining all the available magic attributes, and 
there are a lot of them.  Dain pointed me to that, too.  :)
