Generic Java component invocation interface?

[Jean-Sebastien Delfino]

I'm trying to implement a generic Java 'relay' component that relays 
requests from one binding to another. I may need to inspect and 
transform the request before relaying it.

Is there a way for a component to implement a generic invocation 
interface, get the  invoked operation and input and relay it to a reference?

Thanks
