title: Invalid signature. Expected signature base string, JAVA
body: <p>We are using this piece of code to send request on aweber via oAuth</p>
  
  <pre><code>long unixTime = System.currentTimeMillis() / 1000L;
  OAuthRequest request1 = new OAuthRequest(Verb.GET,"https://api.aweber.com/1.0/accounts/1111/lists/1111/subscribers", service);
  request1.addBodyParameter("ws.op", "create");
  request1.addBodyParameter("email", "account@gmail.com");
  request1.addBodyParameter("name", "ankur");
  request1.addBodyParameter("oauth_token_secret", "mysecret");
  request1.addBodyParameter("oauth_token", "mytoken");
  request1.addBodyParameter("oauth_consumer_key", "mykey");
  request1.addBodyParameter("oauth_signature_method", "HMAC-SHA1");
  request1.addBodyParameter("oauth_nonce", "secret");
  request1.addBodyParameter("oauth_timestamp", String.valueOf(unixTime));
  
  service.signRequest(accessToken, request1);
  Response response1 = request1.send();
  // Create a reader to read Twitter's stream
  BufferedReader reader1 = new BufferedReader(new InputStreamReader(response1.getStream()));
  
  String line;
  while ((line = reader1.readLine()) != null) {
      System.out.println(line);
  }      
  </code></pre>
  
  <p>But we are getting this in response </p>
  
  <pre><code>{
      "error": {
          "status": 401,
          "documentation_url": "https://labs.aweber.com/docs/troubleshooting#unauthorized",

      }
  }
  </code></pre>
  
  <p>Invalid signature. Expected signature base string</p>
  
  <p>I checked my signature, Its same. Dont know why its showing different. </p>
  
  <h2>UPDATE - 1:</h2>
  
  <p>Lots of guys saying my key and access token is invalid, But In my code I am hitting first account URL after that trying to hit another. </p>
  
  <p>like this</p>
  
  <pre><code>  OAuth1AccessToken  accessToken= new OAuth1AccessToken("oauth_token","oauth_token_secret","oauth_token_secret=oauth_token_secret&amp;oauth_token=oauth_token");
    final OAuthRequest request = new OAuthRequest(Verb.GET, ACCOUNT_RESOURCE_URL, service);
    service.signRequest(accessToken, request);
  
    final Response response = request.send();
    System.out.println("Got it! Lets see what we found...");
    System.out.println();
    System.out.println(response.getBody());
  
    System.out.println();
    System.out.println("Thats it man! Go and build something awesome with AWeber and ScribeJava! :) 11111111");
  </code></pre>
  
  <p>and here is the log </p>
  
  <pre><code>  Got it! Lets see what we found...
  
   {"total_size": 1, "start": 0, "entries": [{"http_etag": "\"8c4c161ee1fd3dfg596911c82e9f2feff145907dec2-ca5feee2b7fbb6febfca8af554fg1541ea960aaedb\"", "lists_collection_link": "https://api.aweber.com/1.0/accounts/xxxx/lists", "self_link": "https://api.aweber.com/1.0/accounts/xxxx", "resource_type_link": "https://api.aweber.com/1.0/#account", "id": xxxx, "integrations_collection_link": "https://api.aweber.com/1.0/accounts/xxxx/integrations"}], "resource_type_link" : "https://api.aweber.com/1.0/#accounts"}
  </code></pre>
  
  <p>After this I am running my top code, So is there anything wrong with my key then why its working for first part of code?</p>
