AES Encryption Issue

This is Code on Client (RIM JDE)

AESKey key = new AESKey(128);

EncodedKey encodedKey = SymmetricKeyEncoder.encode(key, "PKCS8" );
System.out.println("Encoded Key Format" + encodedKey.getEncodingAlgorithm());
System.out.println("AES Key Algoritham" + key.getAlgorithm());
System.out.println("Encoded Key Length" + key.getLength());
System.out.println("Encoded Key BitLength" + key.getBitLength());

if(!sendMessage(encodedKey.getEncodedKey())){
System.out.println("Failed to send AES Key");
}

I m encoding the key and transmiting this key to server using UDP.
on server side(UDP server implemented in Java with Certicom API)
decoding the Key in PKCS#8 format to get AES Key


Here is the Code on Server

PKCS8EncodedKeySpec k1spec = new PKCS8EncodedKeySpec(receiveKey());
System.out.println("Encoding Format" + k1spec.getFormat());
SecretKeyFactory skf = SecretKeyFactory.getInstance("AES","Certicom");
SecretKey ssk = skf.generateSecret(k1spec);
Cipher eAESCipher = Cipher.getInstance("AES");
eAESCipher.init(Cipher.DECRYPT_MODE,ssk);


BUt server throw exception
Exception :java.security.spec.InvalidKeySpecException: Invalid key spec

As on client as well as server I chked the encoding Format and it says PKCS#8
then why I am geting this exception.
