Hi Norbert
Since ECB mode is working
then the problem is in setting the same IV initial value in both sides for CBC mode or any other mode that require IV .
don't forget to initialize your cipher in java before encryption and decryption with the "Initial value"
byte[] ivBytes = new byte[]{..,..,..};
IvParameterSpec ivSpec = new IvParameterSpec(ivBytes );
Cipher c = Cipher.getInstance("...","..."/*provider name, u may use Bouncy castle*/);
//in encrption function
cipher.init(Cipher.ENCRYPT_MODE, key, ivSpec);
//in decryption function
cipher.init(Cipher.DECRYPT_MODE, key, ivSpec);
and The example Jeffery sent for Crypto++ code is very helpful
u may send your c and java code
