hello friends,
check these codes..

Code:

import java.awt.*;
 import java.applet.*;
 import java.awt.event.*;
 public class pp extends Applet implements ActionListener
 {
     TextField t;
       Button    b;
     public void init()     
     {
             setLayout(new FlowLayout());
            t= new TextField(10 );
             b = new Button("Send");
         b.addActionListener(this);
             add(t);
             add(b);
       }
      public void actionPerformed(ActionEvent e) 
     {
                String str=t.getText();
         dc a2 =(dc)getAppletContext().getApplet("a2");
                if ( a2 != null ) 
         {
                   a2.append(str);
                }
                else 
         {
                   System.out.println("Applet not found?");
                }
          }
 }

and the 2nd applet code goes here...

Code:

import java.applet.*;
 import java.awt.*;
 import java.awt.event.*;
 /*<Applet code="dc" height=400 width=400></Applet>*/
 public class dc extends Applet
 {
     TextArea t;
     public void init()
     {
         setLayout(new FlowLayout());
         t=new TextArea(5,40);
         add(t);
     }
     public void append(String msg)
     {
         t.setText(msg);
     }
 }

here goes the html codes...

Code:

<HTML><HEAD></HEAD><BODY>
 <APPLET CODE="pp.class"   
         HEIGHT=200 WIDTH=150>
 </APPLET>
 <APPLET CODE="dc.class"  
         HEIGHT=200 WIDTH=400>
 </APPLET>
 </BODY></HEAD>

Don't know why it doesn't works.
Can anyone tell me where i have done mistake here....?
