Folks,
Our strange stack overflow problem has re-occurred. We're looking into
the possibility that the problem is linked to some null pointer
exceptions. Two of the null pointer stacks are shown below - they seem to
be being raised during wsdl generation. Can anyone give us any clues as
to why these errors would occur?
ta,
Tim.
