Problem: Unauthorized to access the document

Hi,

I am using Axis 3 beta version and trying to call a contributed webservice
at www.xmethods.com through internet. Since I behind the firewall, i have
specified proxydetails as argument to jvm with
 -Dhttp.proxyHost=xxx.com -Dhttp.proxyPort=80 -Dhttp.proxyUserName=xxx
-DproxyPassword=yyy 
I am getting the following exception
AxisFault
 faultCode: {http://xml.apache.org/axis/}HTTP
 faultString: (401)Unauthorized to access the document
 faultActor: null
 faultDetail: 
        null: return code:  401
