Debugging with Xerces API

R

Robert Mark Bram

Hi All,

I am accessing a web service whose Java stubs I have generated with
WSAD 5.1. I am getting the error listed below.

It seems to indicate that there was some missing xml.

I want to see the xml request and response messages. Does anyone know
of a tool or config setting I can use to view this? Specifically, can
the xerces API help by providing extra debugging?

Any help would be most appreciated!

Rob

Assuming you're using HTTP (or some protocol over TCP) to communicate
between client and server, you can use something like TCPmon to watch the
traffic going back and forth.
