I'm trying to make a simple Twitter application in Eclipse. I'm getting a "Resource not found" error. I have tried using a simple Java class, as well as a Servlet.
My code: TwitterIntegration.java:
package com.home.social;
import java.io.BufferedWriter;
import java.io.FileWriter;
import java.util.List;
import twitter4j.Query;
import twitter4j.QueryResult;
import twitter4j.Status;
import twitter4j.Twitter;
import twitter4j.TwitterFactory;
import twitter4j.conf.ConfigurationBuilder;
public class TwitterIntegration {
public static void main(String[] args) throws Exception
{
// Create configuration builder and set key, token etc
ConfigurationBuilder cb = new ConfigurationBuilder();
cb.setOAuthConsumerKey("xx");
cb.setOAuthConsumerSecret("xx");
cb.setOAuthAccessToken("xx");
cb.setOAuthAccessTokenSecret("xx");
// Create Twitter instance
Twitter Twitter = new TwitterFactory(cb.build()).getInstance();
// Create file writer and buffer writer
FileWriter fstream = new FileWriter("Twitterstream.txt",true);
BufferedWriter out = new BufferedWriter(fstream);
// Create Query object and set search string
Query query = new Query("");
query.setQuery("#Mumbai");
// Get query result
QueryResult qr = Twitter.search(query);
// Get tweets and write in the file
while(qr.hasNext())
{
qr.nextQuery();
List<Status> tweets = qr.getTweets();
for (Status t: tweets)
{
System.out.println(t.getId() + " - " + t.getCreatedAt() + ": " + t.getText());
out.write("\n"+t.getId()+","); out.write("\t"+t.getText()+",");
out.write("\t"+t.getUser()+",");
}
}
try{ Thread.sleep(1000*60*15);
}catch(Exception e) {}
}
}
