SecureRandom sr = new SecureRandom();
    byte[] keyBytes = new byte[20];
    sr.nextBytes(keyBytes);
    SecretKey key = new SecretKeySpec(keyBytes, "HmacSHA1");
    Mac m = Mac.getInstance("HmacSHA1");
    m.init(key);
    m.update(inputData);
    byte[] mac = m.doFinal();

Copied from 'http://oreilly.com/catalog/javacrypt/chapter/ch06.html', you'll find all other cryptographic information there.
