Re: Fault handling in SOAP 2.1

["William A. Nagy" <na...@watson.ibm.com>]

Jonah,

Could you please post your deployment descriptor?

Also, are you creating an actual SOAP provider, or by provider do you
mean your service implementation (i.e. the class whose methods you are
exposing as a service)?

Have you tried grabbing one of the nightly builds
(http://xml.apache.org/dist/soap/nightly) or building a new version of
SOAP from the CVS tree?  (I tried to recreate your exception with the
newest code, using all of the possible combinations that I could think
of, but was unsuccessful.)

Thanks,
-Bill
