the code they have given is working fine. and i checked and working fine for
me...the problem what you are facing is not the exactly where you have saved
that code.
for eg:,.. i am accessing the page like this :
http://localhost/cf/webservice/ws/solution/wsconsumer.cfm
so obviously the webservice code will be like this for me:
http://localhost/cf/webservice/ws/solution/simple.cfc?wsdl
Check out the same thing for you. the code from where you are accessing and
the code where the webservice is are the same in this code. so like what i
said.
