J2ME program for url access

Aim: - Write a program to access data from a specific URL.      The stream connection is used to connect the application to specific URL by Airtime.

import java.io.*;

import javax.microedition.io.*;

import javax.microedition.lcdui.*;

import javax.microedition.midlet.*;

public class AccessUrl extends MIDlet

{

  private Display display;

  String url = "http://localhost/AccessURL/hello.txt";

  public AccessUrl()

  {

    display = Display.getDisplay(this);

  }

  public void startApp()

{

    Try

{       

      connection(url);

    }

catch (IOException e)

{

      System.out.println("IOException " + e);

      e.printStackTrace();

    }

  }

 

  public void pauseApp(){}

  public void destroyApp(boolean unconditional){}

  void connection(String url) throws IOException

{

    StreamConnection sc = null;

    InputStream is = null;

    StringBuffer buffer = new StringBuffer();

    TextBox access;

    Try

{

      sc = (StreamConnection)Connector.open(url);

      is = sc.openInputStream();

      int chars;

      while((chars = is.read()) != -1)

{

        buffer.append((char) chars);

      }

      System.out.println(buffer.toString());

      access = new TextBox("Access Text", buffer.toString(), 1024, 0);

    }

Finally

{       

      if(is != null)

      {

        is.close();

      }

      if(sc != null)

       {

        sc.close();

      }

    }

    display.setCurrent(access);

  }

}

Output:-
