Re: Exception when invoking axis webservice from c#

have you resolved this?

if not, a couple of other questions for you:
1. what version of AXIS are you using? v1.1 was just released in June, and
includes a number of bigfixes over v1.0.

2. Can you get simple types to transfer?

3. did you check the axis mail archive?
