Bouncy Castle AES wrapper Key issue

[idtyu]

Hi : this is the code:

public String getPasswordKey() {
		return Encoder.encode(passwordKey.getEncoded());
	}

	public void setPasswordKey(String key) {
		Security.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
		try {			
			byte[] keys = Encoder.decode(key.toCharArray());
			this.passwordKey = new SecretKeySpec(keys, KEY_ALGORITHM);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

public String keyWrapper() {
		Security
				.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
		Key SharedKey = secret;
		String key = null;
		char[] preMaster = this.preMaster().toCharArray();
		try {
			PBEKeySpec keySpec = new PBEKeySpec(preMaster);
			SecretKeyFactory factory = SecretKeyFactory
					.getInstance(KEY_ALGORITHM);
			paramSpec = new PBEParameterSpec(salt, 1024);
			this.passwordKey = factory.generateSecret(keySpec);
			Cipher c = Cipher.getInstance(KEY_ALGORITHM);
			c.init(Cipher.WRAP_MODE, passwordKey, paramSpec);
			byte[] wrappedKey = c.wrap(SharedKey);
			key = Encoder.encode(wrappedKey);
		} catch (Exception e) {
			e.printStackTrace();
		}
		return key;
	}

	public Key keyUnwrapper() {
		Security
				.addProvider(new org.bouncycastle.jce.provider.BouncyCastleProvider());
		byte[] wrappedKey = sKey;
		SecretKey unWrapped = null;
		try {
			paramSpec = new PBEParameterSpec(salt, 1024);
			Cipher c = Cipher.getInstance(KEY_ALGORITHM);
			c.init(Cipher.UNWRAP_MODE, passwordKey, paramSpec);
			
			unWrapped =(SecretKey) c.unwrap(wrappedKey, KEY_ALGORITHM, Cipher.SECRET_KEY);
		} catch (Exception e) {
			e.printStackTrace();
		}
		return unWrapped;
	}

The problem i am having right now, is that i cannot store the passwordKey which is the key used to wrap my AES key, and if i did tat, it will give me a parameter unknown error ... anyone has any solution?
