Can any help me in resolving this one?
Try removing http://
from your host url when you get java.net.UnknownHostException
and check your internet connection and the host exists (probably safe with google. . .)
I believe it's a proxy problem. Try to see if you have a proxy definition in your browser and then set it:
ProxySelector.setDefault(new ProxySelector() {
@Override
public void connectFailed(URI uri, SocketAddress sa, IOException ioe) {
throw new RuntimeException("Proxy connect failed", ioe);
}
@Override
public List select(URI uri) {
return Arrays
.asList(new Proxy(Proxy.Type.HTTP,
new InetSocketAddress(proxyHost,
proxyPort)));
}
});
To see if you have proxy definition in IE, go to Tools - Internet Options -- Connections -- Lan Settings
