OpenESB: read message from Normalized Message Router

Question

Good morning,
I have to build a simple Business Monitor System.
I use NetBeans 6.5, Glassfish v2 with OpenESB.
My Question is:
there is a way to read messages exchanged between two different application (for example my CASA application and Salesforce CRM wsdl)?
Obviously all application are attached to the ESB.
I know that all SOAP messages are transformed to Normalized Message (by Normalized Message Router) and then sent over the ESB, so I think there is a way to read all messages (but I didn't find it).
Thanks
Matteo

Thank you Mark,
I modified the test Observer a bit just to dump the message exchange. Actually it seems to work, except for a weird thing: The message count is always 0 for any message exchange I log, like there are no Normalized Messages in the MessageExchangeImpl. Am I missing something obvious? I'm just calling the toString() of the MessageExchage in the run() method of the ObserverLifeCycle class, I'd expect to see some messages sometime.
