RemoteExceptions were used mainly to mark methods as web methods. If
you want to
throw service specific exceptions, delare those additional exceptions as
well in your method
signature. Note that there are restrictions as to what such an exception
can look like.

I suspect that what you get on the client is due to different
implementations interpretting
the spec differently. Your best bet is to NOT throw RemoteExceptions if
an error happens
in your service, but rather service specif exceptions.
