Using base64 in applet

Question

Hey,
I want to use the base64 encoder in my applet but I get faults.
I think the problem is that he doesn't recognize the BASE64Encoder.
This is my code:
//some other imports
import javax.crypto.spec.PBEParameterSpec;
import javax.crypto.spec.PBEKeySpec;
import javax.crypto.*;
import java.security.*;
// This is for BASE64 encoding and decoding
import sun.misc.*;
public class Demo4 extends Applet{
//some code
public String encrypt(String pass, String plaintext)
          throws Exception
          char[] password = pass.toCharArray();
          byte[] ciphertext = plaintext.getBytes();
     //herkend BASE64Encoder niet
          BASE64Encoder encoder = new BASE64Encoder();
          String ciphertextString = encoder.encode(ciphertext);
          return encoder.encode(ciphertext);
This function I want to call in my html page using javascript.
Does anyone know what the problem can be?

Don't use the sun.misc.* classes. They are undocumented, subject to change, and may not be included with all distributions of Java.
There are many alternatives out there for Base64 encoding. I have written one:

You can include it in your applet.
