Well, even though I use the muse API to craft a notification message,
I don't use it to invoke the remote service. If I try to send the
notification message from a command line client it works fine, that's
why I have a feeling that I'm doing something wrong in the way I call
the service inside this first service.
I'll make some tests with other kinds of services to make sure that
the problem isn't with Axis.
thank you
