Hi Josh,
we earlier looked at stackoverflow, we are facing this issue when we use axis implementation of google adwords webservice, instead when we use jaxws implementation it is working fine. I am not sure this is the issue with axis implementation (some where I read that axis overwrites proxy configurations internally)
Please let us know if it is suggested way to use jaxws google-lib (adwords-appengine) files instead of axis api files(adwords-axis)
Thanks.
