Comment réparer la longueur de clé AES invalide?

Je suis en train de travailler sur un basé sur le web texte de chiffrement et de déchiffrement projet sur eclipse(à la suite de Struts 2)

Chaque fois que je rentre le mot de passe et le texte en clair je reçois un Invalide la Longueur de la Clé AES erreur.

La Classe De Service(SymAES.java)

package com.anoncrypt.services;

import java.security.Key;
import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;

import sun.misc.BASE64Decoder;
import sun.misc.BASE64Encoder;

public class SymAES
{
    private static final String ALGORITHM = "AES";
    private static byte[] keyValue= new byte[] { 'T', 'h', 'i', 's', 'I', 's', 'A', 'S', 'e', 'c', 'r', 'e', 't', 'K', 'e', 'y' };

     public  String encode(String valueToEnc) throws Exception {
         System.out.println("The Key byte value"+keyValue );

        Key key = generateKey();
        Cipher c = Cipher.getInstance(ALGORITHM);
        c.init(Cipher.ENCRYPT_MODE, key);
        byte[] encValue = c.doFinal(valueToEnc.getBytes());
        String encryptedValue = new BASE64Encoder().encode(encValue);
        return encryptedValue;
    }

    public  String decode(String encryptedValue) throws Exception {
        Key key = generateKey();
        Cipher c = Cipher.getInstance(ALGORITHM);
        c.init(Cipher.DECRYPT_MODE, key);
        byte[] decordedValue = new BASE64Decoder().decodeBuffer(encryptedValue);
        byte[] decValue = c.doFinal(decordedValue);
        String decryptedValue = new String(decValue);
        return decryptedValue;
    }

    private static Key generateKey() throws Exception {
        //System.out.println("passs value"+pass);

        System.out.println("The Key byte value instde genkey"+keyValue );
        Key key = new SecretKeySpec(keyValue, ALGORITHM);
        return key;
    }

    public  void start(String passcode)throws Exception
    {
        keyValue = passcode.getBytes();
        System.out.println("passcode"+passcode);    
        System.out.println("The Key byte value inside start"+keyValue );
    }
}

Ici est la Classe d'Action(SymEncrypt.java)

package com.anoncrypt.actions;

import com.anoncrypt.services.SymAES;

public class SymEncrypt  {
    private String encrypt;
    private String encrypted;
    private String password;

    boolean TEMP;

    public String execute() throws Exception {
        SymAES ob=new SymAES();
        ob.start(getPassword());

        setEncrypted( ob.encode(getEncrypt()));
        System.out.println("into action class "+getEncrypted());

        if(getEncrypted().equals(null))
             return "error";
        else 
             return "success";
    }

    public String getEncrypted() {
        return encrypted;
    }

    public void setEncrypted(String encrypted) {
        this.encrypted = encrypted;
    }

    public String getEncrypt() {
        return encrypt;
    }

    public void setEncrypt(String encrypt) {
        this.encrypt = encrypt;
    }

    public String getPassword() {
        return password;
    }

    public void setPassword(String password) {
        this.password = password;
    }
}

Et c'est l'erreur
