I think you have confused two different parts of the same section. If a
handler returns false, the runtime stops the handler processing (or
switches to response processing). There is no exception in this case.
It's when a client handler throws an exception that the exception is
propagated up to the client.

This will be easy to do in jaxrpc 2.0 where there are context objects
that the stub can use for this purpose. In the meantime, one way I've
done it for testing handlers is to create a singleton class that stores
data for handlers. It's a simple hack, but allows both the client and
handler objects to get the same data object. There's no Stub api in 1.X
for doing this directly.
