AirportWeather sample

Hello,

When I try to test the AirportWeather sample with Sun ONE Studio 4 ME
(update 1) and kSOAP 1.2 I get an java.io.IOException with the following
output:

I've tried different emulators with the same result.
Does anyone have an idea how I can solve this problem?

Thanks,
