Why is the Etrade API returning a missing parameters error? - oauth

Question

I have successively obtained a request token, and am now using it in conjunction with my consumer key to create the following request
https://us.etrade.com/e/etws/authorize?key=2fc*******c323d6&token=IIrs6BsIrGQ********duC60GAmLq8
where the asterisks have been substituted for my consumer key and request token. I give this as an argument to getAuthorizeURL This returns an ETWSException and output in the terminal reading
ERROR OAuthClientImpl - Mandatory parameters missing
I have the two required arguments for the getAuthorizeURL method, and I am sure they are formatted correctly. Can anyone tell me what is going wrong here?
Also, if it helps to know, calling the getAuthorizeURL causes my default browser to open and brings me to the address that I entered above, but it returns a 404 error.

If you're using the sample code from the Docs.. they are missing 1 piece.
(java)
client = OAuthClientImpl.getInstance(); // Instantiate IOAUthClient
request = new ClientRequest(); // Instantiate ClientRequest
request.setEnv(Environment.SANDBOX); // Use sandbox environment
request.setConsumerKey(oauth_consumer_key); //Set consumer key
request.setConsumerSecret(oauth_consumer_secret); // Set consumer secret
token= client.getRequestToken(request); // Get request-token object
oauth_request_token = token.getToken(); // Get token string
oauth_request_token_secret = token.getSecret(); // Get token secret
request.setToken(oauth_request_token);
request.setTokenSecret(oauth_request_token_secret);
String authorizeURL = null;
authorizeURL = client.getAuthorizeUrl(request);
URI uri = new URI(authorizeURL);
Desktop desktop = Desktop.getDesktop();
desktop.browse(uri);
The Documentation sample forgot to mention, you'll need to set the Token Key/Secret on the Request object, before you make the call the get AuthorizeUri.
request.setToken(oauth_request_token);
request.setTokenSecret(oauth_request_token_secret);
