have written a code which retrieves latest tweets of a particular user and display it in an excel sheet. I want to display more than 20 tweets and went about reading many online available help but was not useful. Can any one help me out?

TwitterServlet.java:

package com.dhruvil.jsw;
import java.io.IOException;
import java.util.ArrayList;
import java.util.List;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.poi.xssf.usermodel.XSSFSheet;
import org.apache.poi.xssf.usermodel.XSSFWorkbook;
import twitter4j.Status;
import twitter4j.Twitter;
import twitter4j.TwitterException;
import twitter4j.TwitterFactory;
import twitter4j.auth.AccessToken;




public class TwitterServlet extends HttpServlet {
private static final long serialVersionUID = 1L;


public TwitterServlet() {
super();
}

protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
String CONSUMER_KEY = "xxx";
request.setCharacterEncoding("UTF-8");
String CONSUMER_KEY_SECRET = "xxx";
String AccessToken = "xxx";
String AccessTokenSecret = "xxx";
response.setContentType("text/html");
response.setContentType("application/PDF");
String input1 = request.getParameter("first");

System.out.println(input1);
if (input1 == null || input1.trim().length() == 0) {
input1 = "You didn't enter any text.";
}
XSSFWorkbook workbook = new XSSFWorkbook();

XSSFSheet sheet = workbook.createSheet("Twitter Sheet");




try{
Twitter twitter = new TwitterFactory().getInstance();
twitter.setOAuthConsumer(CONSUMER_KEY, CONSUMER_KEY_SECRET);
AccessToken oathAccessToken = new AccessToken(AccessToken, AccessTokenSecret);
twitter.setOAuthAccessToken(oathAccessToken);
List<status> status = twitter.getUserTimeline(input1);
List<string> tweets = new ArrayList<string>();

for (Status status2 : status)
{
tweets.add(status2.getText());
System.out.println("---Tweet---"+status2.getText());
}

WriteExcel.writeExcel(tweets, "Tweets.xls");





}catch (TwitterException te){
System.out.println("Error occured "+te);
}
System.out.println("Tweets Retrieved");



super.doPost(request, response);
}

}

I can retrieve 20 tweets and can display in an excel sheet. How to get more tweets and have a pop up in which the excel sheet gets automatically opened with data in it
