what exactly?is this method called anytime that a service inside the

I have no experience with this type ofprogramming, so excuse me for all

What do i have to put inside this Axis2 module and how can i attach it

Do you mean incoming messages to the ODE server?wich type of messages
mex interceptors can capture?
i need to capture messages invocation to each service that compose the
