Subject Re: Dynamically deploying interceptors via JMX
Date Tue, 27 Feb 2007 15:59:19 GMT
So you want the Bus to have the addInterceptor(id) method? Or would that be
the function of the instrumentationManager? It would seem rather odd to me
to have the former. If its the later, you could just make the
InstrumentationManager ApplicationContextAware, no? (of course I probably
don't understand all the ins and outs quite yet...)
