reading .txt file from URL

[bokz06]

i think i have converted my application to an applet..... it use to read lines from a .txt file i have on my hard drive but now i want it to read a .txt file from a URL:

import java.awt.*;
import java.awt.event.*;
import javax.swing.JButton.*;
import javax.swing.event.ListSelectionEvent;
import java.net.*;
import java.io.*;


public class RosterSorter extends JApplet {

 
  ArrayList<String[]> rosterList = new ArrayList<String[]>();

  // The TableModel controls all the data:
  class MyTableModel extends AbstractTableModel {
        private String[] columnNames = { "Name" , "Age", "Pos", "Nat", "St", "Tk", "Ps", "Sh", "Ag", "Kab", "Tab", "Pab", "Sab", "Gam", "Sub", "Min", "Mom", "Sav", "Con", "Ktk", "Kps", "Sht", "Gls", "Ass", "DP", "Inj", "Sus"};
        

        public int getColumnCount() {
            return columnNames.length;
        }

        public int getRowCount() {
            return rosterList.size();
        }

        public String getColumnName(int col) {
            return columnNames[col];
        }

      
        public Object getValueAt(int row, int col) 
        {    
             return rosterList.get(row)[col];
                              
        }

        
    }



     [B]private void textRead() [/B]
  {
     BufferedReader br = null;
     
     try { 

    URL                url; 
    URLConnection      urlConn; 
    DataInputStream    dis; 

    url = new URL("http://afterextratime.net/game/ita/1/Laz.txt"); 

    urlConn = url.openConnection(); 
    urlConn.setDoInput(true); 
    urlConn.setUseCaches(false); 

    dis = new DataInputStream(urlConn.getInputStream()); 
    String s; 
  
      while ((s = dis.readLine()) != null) { 
      String [] rowfields = s.split("[ ]+");
        rosterList.add(rowfields);
        s = dis.readLine(); 
    } 
    dis.close(); 
    } 
    catch (MalformedURLException mue) {} 
    catch (IOException ioe) {} 
  } 

public void init() {
      textRead();
      
    Container cp = getContentPane();
     TableModel myData = new MyTableModel(); 
           JTable table = new JTable(myData);
    
    table.setSelectionMode(ListSelectionModel.MULTIPLE_INTERVAL_SELECTION);
            table.setAutoCreateRowSorter(true);
            table.setRowSelectionAllowed(true);
            table.setColumnSelectionAllowed(false);
            
        
    cp.add(new JScrollPane(table));
    
    
  }

  

  public static void run(JApplet applet, int width, int height) {
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.getContentPane().add(applet);
    frame.setSize(width, height);
    applet.init();
    applet.start();
    frame.setVisible(true);
  }
}

the JTable shows up but it it wont read the file and display the values in the table :S although the file is virtually identical to the one on my harddrive.

Hello,

Heres another way to read the file:

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import java.net.MalformedURLException;
import java.net.URL;

public class TestURLReading {

  static protected void readURL() {
    String u = "http://afterextratime.net/game/ita/1/Laz.txt";
	URL url;
    InputStream is;
    InputStreamReader isr;
    BufferedReader r;
    String str;

    try {
      System.out.println("Reading URL: " + u);
      url = new URL(u);
      is = url.openStream();
      isr = new InputStreamReader(is);
      r = new BufferedReader(isr);
      do {
        str = r.readLine();
        if (str != null)
          System.out.println(str);
      } while (str != null);
    } catch (MalformedURLException e) {
      System.out.println("Invalid URL");
    } catch (IOException e) {
      System.out.println("Can not connect");
    }
  }

  static public void main(String args[]) {
         readURL();
  }
}

Tested and working perfectly.

These below code you can use for readin text file from URL.

String charset = "utf-8";
URL url = new URL(your text file URL);
URLConnection conn = url.openConnection();
conn.setDoOutput(true);
InputStream inputStream = null;
inputStream = url.openStream();
StringBuffer s = new StringBuffer();
if(charset==null"".equals(charset)){
charset="utf-8"; }
String rLine = null;
BufferedReader bReader = new BufferedReader(new InputStreamReader(inputStream,charset));
PrintWriter printWriter = null;
FileOutputStream fo = new FileOutputStream(fileName);
OutputStreamWriter writer = new OutputStreamWriter(fo, "utf-8");
printWriter = new PrintWriter(writer);
while ( (rLine = bReader.readLine()) != null) {
String line = rLine;
int str_len = line.length();
if (str_len > 0) {
s.append(line);
printWriter.println(line);
printWriter.flush();

I wrote one example to download an image URL to your local PC. You can use this java code

You can also check this code to download TEXT file from URL
