why is the servername secret. This shouzld be a public server.

Try the following program

import javax.crypto.Cipher;
import javax.crypto.spec.IvParameterSpec;
import javax.crypto.spec.SecretKeySpec;

public class CheckCrypto {
    public static void main(String[] args){
        String cryptoAlg = "AES";
        try{
            SecretKeySpec keyspec = new SecretKeySpec(new byte[32], cryptoAlg);
            Cipher c = Cipher.getInstance(cryptoAlg + "/CBC/NoPadding");
            c.init(Cipher.ENCRYPT_MODE, keyspec, new IvParameterSpec(new byte[16]));
        }
        catch(Exception e){
            System.err.println("************ The Java Virtual Machine can't handle strong cryptography.\n************ This will lead to problems with some services and subsystems!");
        }

    }
}

If you get the exception-message, you still need to install the
unlimimted strength cryptography policy files.
