Any help/suggestions much appreciated. 

Hi, I just ran this code using a fresh downloaded Twitter4j 3.0.3. A minor adjustment: getStatuses() becames getTweets(). That's all. I never had a  "cannot convert twitter to twitter" error. Just "getStauses() do not exist, fixed as i said. I  got the time line and the search result. Also i changed the  query to "love". The other one was a no hit. Also formated so in forum when one copy the code iyt wont be in just one line.

those are the files I have in my code folder:

twitter4j-async-3.0.3.jar

twitter4j-core-3.0.3.jar

twitter4j-examples-3.0.3.jar

twitter4j-media-support-3.0.3.jar

twitter4j-stream-3.0.3.jar

CODE EDITED:

I just cleaned the code, leaving just the necessary, also used generics in timeline method.

2. List<Status>statuses = null;
3. 
   
4. TwitterFactory twitterFactory;
5. Twitter twitter;
6. 
   
7. void setup() {     
8.   size(100, 100);    
9.   background(0); 
10.   
11.   connectTwitter();    
12.   getTimeline();  
13.   getSearchTweets();
14. }  
15. 
    
16. void draw() {     
17.   background(0);
18. }  
19. 
    
20. 
    
21. 
    
22. 
    
23. // Initial connection
24. void connectTwitter() {  
25.   ConfigurationBuilder cb = new ConfigurationBuilder();  
26.   cb.setOAuthConsumerKey("XxXxXxXxXxXxXxXxX");
27.   cb.setOAuthConsumerSecret("XxXxXxXxXxXxXxXxX");
28.   cb.setOAuthAccessToken("XxXxXxXxXxXxXxXxX");
29.   cb.setOAuthAccessTokenSecret("XxXxXxXxXxXxXxXxX"); 
30.     
31.   twitterFactory = new TwitterFactory(cb.build());    
32.   twitter = twitterFactory.getInstance();  
33.   
34.   println("connected");
35. } 
36. 
    
37. // Get your tweets
38. void getTimeline() {     
39.   try {        
40.     statuses = twitter.getUserTimeline();
41.   }   
42.   catch(TwitterException e) {         
43.     println("Get timeline: " + e + " Status code: " + e.getStatusCode());
44.   }     
45.   for (Status status:statuses) {               
46.     println(status.getUser().getName() + ": " + status.getText());
47.   }
48. }  
49. // Search for tweets
50. 
    
51. void getSearchTweets() {           
52.   try {        
53.     Query query = new Query("love");            
54.     QueryResult result = twitter.search(query);              
55.     for (Status status : result.getTweets()) {              
56.       println("@" + status.getUser().getScreenName() + ":" + status.getText());
57.     }
58.   }   
59.   catch (TwitterException e) {            
60.     println("Search tweets: " + e);
61.   }
62. }

(and TwitterFactory) for that matter.

I have the same libraries,,, I think it's something to do with the line : List<Status>statuses = null; 

-- I don't understand that line; I'm guessing it's calling a class from Java?

Those classes Status and TwitterFactory are defined in the library (twitter4j).

The error reads:

Cannot find a class or type named "List"

Have we figured out why this error is popping up and a fix for it? I'm trying to get my Twitter based app to work again with Twitter4j3.0.3. So I'm trying to run this example just to get something to work so I can go back and fix things in my program. I too dragged and dropped vk's listed files on to the sketch and the files are showing up in my core folder.

Thanks,

import java.util.*;

to the beginning of the code, and it should work. Not related to twitter4j...

there is a technical FAQ for that in wiki. 

Now I have a slew of other issues... but that might be due to my firewall and proxies. i'll get back to you if it's a twitter4j issue.
