access denied (java.net.SocketPermission

When I run the code below as an applet I get this message:
Hello java

there was a problem

access denied (java.net.Socke tPermission yahoo.com resolve)

But when I take the same code for reading the url as an application it
works.

What do I need to do???

............
import java.net.*;
import java.io.*;

import java.applet.App let;
import java.awt.Graphi cs;

public class HelloWorld extends Applet {
public void paint(Graphics g) {
g.drawString("H ello world!", 50, 25);
System.out.prin tln("hello java");


try{

URL url = new URL("http://yahoo.com");
URLConnection connection = url.openConnect ion();

PrintWriter out = new PrintWriter(
connection.getO utputStream());
out.println("st ring=stringToRe verse");
out.close();

BufferedReader in = new BufferedReader(
new InputStreamRead er(
connection.getI nputStream()));
String inputLine;

while ((inputLine = in.readLine()) != null)
System.out.prin tln(inputLine);

in.close();

}
catch ( Exception e)
{
System.out.prin tln("there was a problem");
System.out.prin tln(e.getMessag e());
}


}
}
