Watson Conversation Service - Unauthorized: Access is denied due to invalid credentials

I've tried to access the Watson Conversation Service via a Java Application. Therefore I created the Service on Bluemix an wrote a small Application.

package de.kkh.comp.WatsonDemo;

import java.util.Collection;
import java.util.HashMap;
import java.util.Map;
import java.util.Set;
import java.util.Map.Entry;

import com.ibm.watson.developer_cloud.conversation.v1.ConversationService;
import com.ibm.watson.developer_cloud.conversation.v1.model.MessageRequest;
import com.ibm.watson.developer_cloud.conversation.v1.model.MessageResponse;

public class App {

private static final String USERNAME = "{USERNAME}";
private static final String PASSWORD = "{PASSWORD}";
private static final String WORKSPACE_ID = "{WORKSPACE_ID}";

public static void main(String[] args) {
    ConversationService service = new ConversationService(ConversationService.VERSION_DATE_2017_02_03);
    service.setUsernameAndPassword(USERNAME, PASSWORD);

    MessageRequest newMessage = new MessageRequest.Builder().inputText("Hallo").context(new HashMap<String,Object>()).build();

    MessageResponse response = service.message(WORKSPACE_ID, newMessage).execute();

    System.out.println(response);
}
}

I expect that i get a simple answer of the Watson Service.

If I run the Application I got an Not Authorized Exception, although i use the credentials which are given by Bluemix.

I haven't any clue why i got this Exception. Any Ideas?

Solution

  • Problem solved.

    I used a german location. Therefore the API-Endpoint needs to be https://gateway-fra.watsonplatform.net/conversation/api, instead of the Default-URL.

    The Constructor of ConversationService uses the Default-URL, which is https://gateway.watsonplatform.net/conversation/api. To change the Endpoint it's necessary to call: service.setEndPoint("https://gateway-fra.watsonplatform.net/conversation/api")

    After I did that, everthing worked fine.
