XMLCipher and PKCS#5Padding

Question

Hello,
how can I change the padding scheme that the XMLCipher object is using?
For encryption I use:
          SecretKeyFactory desFactory = SecretKeyFactory.getInstance(algorithm);
          DESedeKeySpec desedekeySpec = new DESedeKeySpec(passphraseBytes);
          SecretKey encKey = desFactory.generateSecret(desedekeySpec);
          Cipher cipherObj = Cipher.getInstance("DESede/CBC/PKCS#5Padding");
          cipherObj.init(opmode, encKey);
          CipherInputStream cis = new CipherInputStream(plaintextBytes, cipherObj);and for decryption I use:
        Key symmetricKey = GenerateDataEncryptionKey();
        String algorithmURI = XMLCipher.TRIPLEDES;
        XMLCipher xmlCipher = XMLCipher.getInstance(algorithmURI);
        xmlCipher.init(XMLCipher.DECRYPT_MODE, symmetricKey);
     xmlCipher.doFinal(document, encryptedDataElement);If I use the second code to decrypt (DESede, CBC, PKCS#5 padding, BASE64)-Characters, I get an error:
Exception in thread "main" org.apache.xml.security.encryption.XMLEncryptionException: Given final block not properly padded
Original Exception was javax.crypto.BadPaddingException: Given final block not properly padded
XMLCipher.TRIPLEDES is DESede with CBC but I think the XMLCipher doesn't use PKCS#5Padding.
How can I set the padding of the XMLCipher object?

Thanks, but when I use
Cipher.getInstance("DESede/CBC/ISO1026Padding")it says
java.security.NoSuchAlgorithmException: Cannot find any provider supporting DESede/CBC/ISO1026Padding at javax.crypto.Cipher.getInstance(DashoA13*..)
...so it doesn't encrypt anything.
I read this standard:
http://www.w3.org/TR/xmlenc-core/#sec-Alg-Block
But there is nothing concrete about the padding. What should I use as the parameter for Cipher.getInstance(parameter); so that the XMLCipher can decrypt it?
thanks a lot for your time!
