Using Example from behind a proxy

LudgerHeck — Fri, 25 Apr 2014 07:10:07 GMT

I am trying to get the example to run from behind a proxy, and somehow I seem to be missing something crucial.
Below is, what I've tried so far
I get

--- result ---

--- end of result ---

This seems to me to show that I can pass the proxy in an ordinarily way but somehow not when calling map.getLayers
What am I missing?
Thanks for any help

You may need to work with your network admin to work out why this is failing. It should be a case of using the following code:

ProxySetup proxySetup = new ProxySetup();
String proxyHost = "myproxy.domain.com";
int proxyPort = 8080 ;
UserCredentials proxyCredentials = new UserCredentials();
proxyCredentials.setUserAccount("userName", "password");

try {
ProxySetup.setupProxy(proxyHost, proxyPort, proxyCredentials);
}
catch (EsriSecurityException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}

This doesn't look too far from what you are already trying though.
