Encryption AES 128 with 2 different Result

I'am trying to encrypt a String using AES-128 algorithm with given Key.

Implemented by Java, I used the solution here.

public static void main(String[] args) {
    String key = "Bar12345Bar12345"; // 128 bit key
    String initVector = "RandomInitVector"; // 16 bytes IV

    System.out.println(encrypt(key, initVector, "System")));
}

Result:

encrypted string: iHvz04u8X7FPo7yagSLthA==

The above result is not what I want, I expect ZJfsFFLjl6YS0Xys5OUVIA== to be the encrypted value of System.

Like the flowing Test On : http://aesencryption.net/

enter image description here

Any propositions?

Your Java code is using an IV, while the web based encryption is not using one. For secure purposes, you should use a random IV so that encrypting the same data twice with the same key doesn't result in the same ciphertext. But if your requirement is to get the same result as from the web based one, leave out the initialization vector completely.
