Is there a simple way to set a proxy host and port in Jersey 1?

Question

Specifically, the version I am using is Jersey 1.19. Currently this is what I am doing:

Client client = Client.create();
client.getProperties().put(ApacheHttpClientConfig.PROPERTY_PROXY_URI, "myhost:myport");

However, this didn't work for me since I got an UnknownHostException:

com.sun.jersey.api.client.ClientHandlerException: java.net.UnknownHostException:

Help is much appreciated.
