Unfortunately not. The JavaProvider, if my memory is correct,
catches the exception and changes it into an AxisFault before
it gets back to the chains.
But even if it did get back to the provider chain it would still
not get back to the transport one, at least not with Axis 1.0.
The onFault method is only called on the handlers in the current
chain, the AxisServer allows the AxisFault to continue unimpeded
once the current chain has handled it.
I'm not sure if this is the intended behaviour but it is certainly
the implemented one. I would have hoped for something more like
the network streams or jboss' invocators.

I have my own EJBProvider that dynamically exposes a group of our
session beans as ports within a service. When this calls the invoked
method it catches the InvocationTargetException and wraps a serialised
version of the exception in an AxisFault.
The generated proxy code then checks the axis fault to see if it contains
one of the expected exceptions and then throws it.
I also had to tweak the generators to prevent generation of the derived
axis faults.
I'm away to Paris this weekend but I'll send you some more information
on Tuesday when I return.
