Twitter 4j with Netbeans

Question

First time poster, but I\'m really stuck. I\'m working on a little project and I\'m trying to send out a tweet using a netbeans project. I\'m using twitter4j and it seems like

Answer 1

Could I suggest an alternative route..

I have recently been messing around with twitter4j and I approached this slightly differently - I found a nice and easy way to authenticate the client using a ConfigurationBuilder object and passing this to the factory that is getting the instance of the Twitter object you need.

package main;

import twitter4j.Twitter;
import twitter4j.TwitterFactory;
import twitter4j.TwitterStream;
import twitter4j.TwitterStreamFactory;
import twitter4j.conf.ConfigurationBuilder;

public class Base {

    protected Twitter twitter;
    //protected TwitterStream twitterStream;
    private ConfigurationBuilder configBuilder;

    public Base(){

        configBuilder = new ConfigurationBuilder();
        configBuilder.setDebugEnabled(true);        
        configBuilder.setOAuthConsumerKey("[consumer key here]");
        configBuilder.setOAuthConsumerSecret("[consumer secret key here]");
        configBuilder.setOAuthAccessToken("[OAuthAccessToken here]");
        configBuilder.setOAuthAccessTokenSecret("[secret OAuthAccessToken here]");

        //use the ConfigBuilder.build() method and pass the result to the TwitterFactory
        TwitterFactory tf = new TwitterFactory(configBuilder.build());
        //you can now get authenticated instance of Twitter object.
        twitter = tf.getInstance();
    }
}

You could then extend this class with sub classes that implement the functionality you require or just create the ConfigurationBuilder/TwitterFactory/Twitter objects elsewhere in your code.

Below I have implemented a class that creates status' and can return the Status object that holds additional information such as createdAt() and the ID etc etc.

package main;

import twitter4j.Status;
import twitter4j.TwitterException;

public class StatusUpdater extends Base{   

    public StatusUpdater(){}

    public Status updateStatus(String statusToUpdate) throws TwitterException{
        Status status = twitter.updateStatus(statusToUpdate);
        System.out.println("statusToUpdate: " + status + ".");
        return status;
    }
}

Then you can use the following statement to create the status. This can be done from mbean/ejb/servlet etc.

     try {
            StatusUpdater statusUpdater = new StatusUpdater();
            String statusTextToSet = "test status";
            Status updatedStatus = statusUpdater.updateStatus(statusTextToSet);
            System.out.println("Created at: " + updatedStatus.getCreatedAt());
        } catch (TwitterException tex) {
            System.out.println(tex.getErrorMessage());
        }

Answer 2

Your code looks ok. Have you confirmed your definitely using the correct consumer key and secret for your app? Try twitter.verifyCredentials() to see if you get the same error, or a more specific error.

If you're correcting to the net via a proxy, you will need to include your proxy settings to allow the connection to succeed, details can be found here http://twitter4j.org/en/configuration.html#HTTP%20proxy%20server

As an aside, you may want to remove you access token and secret from your post, if they're still valid then someone could login to your account with them.
