Subject Using loggingInterceptor
Date Wed, 23 May 2007 23:25:13 GMT

Hi -

I would like to use the loggingInterceptor to trace the problem of why messages are getting
delivered. The example on the activemq site describes how to use the plugin with
xbeans configuration.

I use Spring (2.0) configuration of active brokers - is there a simple example
of how to insert the loggingInterceptor into my configuration without using 
xbean style configuration?

Thanks,

/U
