Here's an example from the Apache site for a proxy w/o credentials:

http://hc.apache.org/httpcomponents-client-ga/httpclient/examples/org/apache/http/examples/client/ClientExecuteProxy.java

(From http://hc.apache.org/httpcomponents-client-ga/examples.html)

You are getting the error because you are passing in a username/password and don't need to.

The WARN messages are coming from the logger (http://hc.apache.org/httpcomponents-client-ga/logging.html) - depending on how you have your logger set up you could just ignore that.

Having spent WAY too much time dealing with trying to make a Java application deal with proxy servers, I can tell you that using a tool such as Proxifier ( http://www.proxifier.com/ for Mac OS X and Windows) or CNTLM ( http://cntlm.sourceforge.net/) was much easier, more flexible, easier to debug, and kept the code clean.
