No data being returned

[Dan]

Our small user group is trying to learn how to use web services and we
picked a small project to start with.  We want to write a client that gets
data from an existing web service and then write our own server that mimics
the existing service.

I'm trying to write client code to use the GetWeatherReport service from
http://www.webservicex.net/usweather.asmx  , but I am not getting any data
in the return.  I get the SOAP reply, but the return string only has the
tags, no values.  When I submit the zipcode via the webpage I do get
weather data.

It appears that the service is not recognizing the input variable ZipCode
because if I name it to something else (like ZipCode2) I get the same result.

I am including the java class and the capture of the request and response.
