Hi ,

      Please find the code below.

public HttpResponse oauth2Login(UserCredentials userCredentials)
  {
    HttpResponse response = null;
    this.userCredentials = userCredentials;
    String loginHostUri = "https://" + userCredentials.loginInstanceDomain + OAUTH_ENDPOINT;
    
    try
    {
      HttpClient httpClient = new DefaultHttpClient();
      HttpPost httpPost = new HttpPost(loginHostUri);
      StringBuffer requestBodyText = new StringBuffer("grant_type=password");
      requestBodyText.append("&username=");
      requestBodyText.append(userCredentials.userName);
      requestBodyText.append("&password=");
      requestBodyText.append(userCredentials.password);
      requestBodyText.append("&client_id=");
      requestBodyText.append(userCredentials.consumerKey);
      requestBodyText.append("&client_secret=");
      requestBodyText.append(userCredentials.consumerSecret);
      
      StringEntity requestBody = new StringEntity(requestBodyText.toString());
      requestBody.setContentType("application/x-www-form-urlencoded");
      httpPost.setEntity(requestBody);
      httpPost.addHeader(prettyPrintHeader);
      response = httpClient.execute(httpPost);
      
      System.out.println("\nResponse is : " + response);
      
      if(response.getStatusLine().getStatusCode() == 200)
      {
        InputStreamReader inputStream = new InputStreamReader(response.getEntity().getContent());
        oauth2Response = gson.fromJson( inputStream,OAuth2Response.class );
        restUri = oauth2Response.instance_url + REST_ENDPOINT +"/v" + this.userCredentials.apiVersion +".0";
        
        System.out.println("\nSuccessfully logged in to instance: " + restUri);
        oauthHeader = new BasicHeader("Authorization", "OAuth " + oauth2Response.access_token);
      }
      else
      {
        System.out.println("An error has occured.");
        System.exit(-1);
      }
    }
    catch (UnsupportedEncodingException uee)
    {
      uee.printStackTrace();
    }
    catch (IOException ioe)
    {
      ioe.printStackTrace();
    }
    catch (NullPointerException npe)
    {
      npe.printStackTrace();
    }
    return response;
  }

      I am using the same code as provided in the DataBase.com introduction document.

Thanks

Hi ,

    One of my friend found the problem.I did setup and implemented the sample code properly as per document.

    But while passing the password I used to  give password only .

    But in Salesforce we need to password+security token  as password.

Thanks
