使用java的twitter应用程序

我试图在Eclipse中创建一个简单的Twitter应用程序。我收到一个“未找到资源”错误。我尝试过使用一个简单的Java类和一个Servlet

我的代码：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) {} 
        } 
    }

您缺少jar文件。您必须安装/下载并将其添加到项目中。

请发布完整的stacktrace。对不起，stacktrace是什么？我已经在这里发布了完整的代码。我已经编辑了语法和格式的问题。
