I have the exact same problem as the OP 4 years later.
I could use wsimport to generate the web service
Java classes, but could not call the web service from Eclipse or from the command line using a jar. I got the same error as the OP...
That's the error you get if your computer cannot reach the WSDL (either because your internet is down, or you are behind some firewall, or whatever).
Any updates on a solution?
I switched my internet connection to the "guest" network instead of the company network, and everything worked. However, I would rather not have to do this every time I want to use a web service. There is a company proxy that we can use to access the internet freely while still remaining on the company network, and when I specify it in my browser (i.e.
http://windows.microsoft.com/en-us/windows/change-internet-explorer-proxy-server-settings#1TC=windows-7), it allows me to go wherever BUT the web services still don't work! Do Java programs just simply ignore the proxy setting on your computer?
