Question

I’m behind a squid HTTP proxy requiring authentication and want to make API requests to an external server. However when I do so, I get the following error :

Caused by: java.io.IOException: Unable to tunnel through proxy. Proxy returns “HTTP/1.0 407 Proxy Authentication Required”

I’ve tried setting the proxy configuration by going to Control Panel > Java > Network Settings, but to no avail.
How to solve this?

Answer 1

You should set the proxy-settings in java.

System.getProperties().put("http.proxyHost", "someProxyURL");
System.getProperties().put("http.proxyPort", "someProxyPort");
System.getProperties().put("http.proxyUser", "someUserName");
System.getProperties().put("http.proxyPassword", "somePassword");
